THE  imYNCIIOPIIORA  OF  AMEIiICA,  NORTH  OF  MEXICO. 
By  John  L.  LeConte,  assisted  uy  Geouoe  II.  IIonx.* 

PREFACE. 

The  task  that  I  have  attempted  to  perform  in  tlic  present  memoir,  is  a 
very  dirticult  one,  and  I  feel  tliat  it  has  been  accomplislied  very  imperfectly. 

It  is,  namely,  from  the  study  of  the  very  small  material  represented  in 
the  fiuina  of  temperate  North  America,  to  induce  entomologists  to  investi- 
gate those  Coleoptcra,  which  have  been  heretofore  classed  as  Curculionidie 
and  some  allied,  but  ill-defined  families,  from  a  completely  new  standpoint, 
whereby  they  become  isolated  from  all  other  Coleoptera. 

The  characters  which  render  necessary  this  isolation  of  the  Hhyncho- 
phora  have  been  already  exposed  by  me  in  some  sliort  memoirs,!  and 
their  value  has  been  recognized  by  several  systematists  of  excellent  ai)illty, 
although  not  to  the  extent  to  which  I  hope  the  present  effort  will  render 
them  acceptable.  These  characters  are  mainly  to  be  found  in  tlie  form  of 
the  basi-lateral  elements  of  the  head  and  prothorax  on  the  under  surface  of 
the  bodj',  and  will  be  detailed  in  the  Introduction. 

By  these  peculiarities  of  structure,  as  well  as  by  their  food,  tlio  Rhyn- 
chophora  ai'c  restricted  to  a  more  uniform  type  of  organization  than  is  exhi- 
bited in  the  n<irmal  Coleoiitera;  but  at  the  same  time  being  represented  by 
an  immense  number  of  species,  the  generic  modifications  are  very  varied. 
The  difficulty  of  tabulating  these  generic  forms  in  a  manner  to  exhibit  their 
relations  to  each  other  is  therefore  greatly  increased. 

I  have  previously  expressed  my  opinion  that  the  Rhynchophora,  being 
the  lowest  type  of  Coleoptera,  arc  tlierefore  geologically  the  oldest.  Re- 
garding then  the  fixity  of  insect  types,  as  shown  by  the  resemblance  of  an- 
cient forms  to  those  of  the  present  time,  the  imiformity  in  food  and  manner

of  life,  and  the  iinmenso  uumbor  of  gencm  in  U»is  complex,  with  which  we 
are  deiilini,',  wc  Imve  ii  right  to  expect  thiit  there  Avill  be  ii  proporlionnlly 
larj^er  .siirvivul  oriiii('lmnu;(Hl  (U'sceiuliints  of  those  species  or  scneni  wliicli 
were  llrsl  iiilnxliu'cd.  \V'e  will,  theniore,  hav(^  ii  more  pert'ccl  series  of 
conu(!ctiiii5  forms  ihiin  ctin  he  foiin'l  In  other  orders  of  insects,  whoso 
melliods  of  life  expose  them  to  llie  inHiiences  of  destruction  or  modillcation 
by  exierniil  eircumsliuiecs. 

Nevertheless,  the  arrangement  which  I  luivo  adopted,  will  show  in  the 
larger  groups  or  tribes,  a  dominance  within  the  liuiits  of  each  trib(>  of  one 
typical  modilication  of  structure,  with  vni'iutions  in  tin-  direction  of  modi- 
fications which  become  dominant,  and  definitive  in  other  tribes. 

ll  thus  comes  to  pass  that,  neglecting  the  essential  clianuMersof  the  tribe, 
to  which  the  species  maj'  propcily  belong,  the  delinitiou  of  the  genus  will 
approximate  in  language  very  closely  to  that  of  some  otlier  genus,  belong- 
ing to  a  very  distinct  pait  of  the  series. 

In  otlier  words,  the  giMicra  belonging  to  several  tribes  will  agree  Avith 
each  other  in  similar  characters  of  less  value  than  the  tribal  characters. 

What  I  have  just  said  regarding  gener't  is  equally  true  in  respect  to 
species.  The  form,  color  and  sculpture  in  many  instances  are  repeated  in 
tribes  which  from  their  geographical  distribution  and  method  of  life  can- 
not be  sui>posed  to  have  anj'  immediate  genetic  derivation.  Instances  of 
this  kind  of  resemblance  will  be  mentioned  both  in  the  Introduction,  and 
in  the  body  of  the  memoir. 

1  have  no  theory  to  i)roi)ound  regarding  this  very  C(miplex  system  .;' 
cross  resemblances.  They  are  certainly  not  the  result  of  mimicry,  and  pro- 
bably not  of  natural  selection,  or  any  other  name  of  an  idea  which  has  yet 
been  suggested.  A  deeper  insight  into  the  phenomena  of  organic  nature, 
which  may,  perhaps,  be  acquired  by  our  successors  would  give  us  a  more 
reasonable  explanation  of  these  resemblances.* 

My  best  thanks  arc  due  to  my  excellent  collaborator.  Dr.  G.  II.  Horn, 
for  his  careful  study  and  classification  of  the  himily  Otiovhynchida>,  cer-

INTRODUCTIO:Nr. 


Rhyncliophorous  Coleoptera  aie  those  in  which  tlic  posterior  liiteral 
elements  of  the  hciul*  and  prothoraxf  coalesce  on  the  median  line  of  the 
under  surface  of  the  hody,  so  as  to  unite  by  a  single  suture. 

To  the  first  of  these  characters  there  is  no  exception  in  the  wide  ranixe 
of  the  existing  Coleopterous  insects  ;  to  the  second  tliere  are  two  iiotaMe 
discrepancies.  The  first  is  Nematidiam.X  commonh"  classed  with  the 
CoJydiidie,  the  other  is  the  genus  Cos.typhit.!>,'/,  which  has  been  considered 
as  belonging  to  the  Teiiebrionidce,  from  the  other  members  of  which  it 
differs,  not  only  by  the  structure  of  the  under  surface  of  the  prosternum, 
but  by  other  characters,  which  require  future  study  for  a  proper  ai)precia. 
tion  of  their  imporlain-e. 

I  might  rest  llic  definition  of  the  Kiiynchoi)hora  at  this  point,  and  jiro- 
ceed  to  indicate  the  ditterent  series  and  families  into  which,  accordinu' to  tlu' 
system  I  have  developed,  these  insects  should  be  divided,  but  before  doing 
so,  there  appear  to  me  certain  relations  between  the  members  of  this  sub- 
order, which  are  well  worthy  of  attention;  and  certain  cliaractcrs  which  I 
have  not  had  time  to  investigate  fully,  but  which  are  indicated  for  tlu' 
guidance  of  tliose,  who  will  in  future  adopt  the  views  herein  set  forth. 

Tliere  are  also  certain  characters  conunon  to  all,  or  nearly  all  Rhyiichoph- 
ora,  most  of  which  I  have  mentioned  in  the  two  essays  cited  below,! 
but  which  for  convenience  may  be  here  briefly  recapitulated  : 

1st.  There  are  no  soft,  larval,  or  imperfectly  chitinized  forms,  or  forms 
with  short  elytra,  exposed  wings,  or  greatly  multiplied  antennal  joints, 
such  as  are  of  frequent  occurrence  among  the  normal  Coleojjtera. 

2(1.  There  are  none  in  whicii  the  side  pi(>ces  of  the  iirothoiax  are  separated 
bj'  suture  from  the  pronotum,  au'l  very  few  in  which  even  the  lateral 
margin  is  indicated;  in  many  the  prosternal  sutures  are  distinct,  liut  in 
some  even  these  are  obliterated. 

3d.  In  none  are  the  front  coxal  cavities  open  posteriorly,  though  in  some

4lh.  The  ventral  segments  never  exceed  live  in  number,  and  the  first 
and  second  are  usually  larger  and  more  closely  connected,  fre(iucntl\'  even 
connate,  with  partially  obliterated  suture;  the  fifth  is  sometimes  k)nger 
than  the  fourth,  sometimes  about  equal  to  it. 

."ith.  When  there  is  any  appreciable  dillerenco  Ixjtwcen  the  sexes,  it  is 
usually  manifested  by  a  greater  elongation  of  the  beak  of  the  9  ■?.  indi- 
cating its  use  as  an  accessory  organ  of  generation,  for  making  the  jjcrfoia- 
tion  in  which  tlie  egg  is  subsequently  placed  by  the  soft  oviiiositor,  and 
pushed  down  by  the  beak. 

(ilii.  The  other  sexual  difTerence  is  in  the  addition  of  a  small  dorsal  (or 
anal)  segment  to  the  ,J^c5^;  this  character  is,  however,  not  oiivious  in 
several  ftunilics,  the  morphological  representative  of  this  anal  segment 
being  completely  retracted  and  covered  by  tlie  pj'gidium.  In  others  this 
segment  is  visible  only  from  heneatli,  simulating,  therefore,  a  sixth  ven- 
tral. 

7th.  The  very  rare  occurrence  of  articulated  movable  spurs  at  the  end 
of  the  tibia';  it  is  seldom,  indeed,  that  more  than  one  fixed  mucro  occurs, 
and  in  the  species  in  which  the  tarsi  are  inserted  laterally  near  the  tip,  this 
mucro  becomes  frecpicntly  ehmgated  and  curved  ;  the  outer  angle  of  the 
tip  is  in  these  instances  (pnte  ofien  i)rolonged  into  a  curved  digitation,  like 
the  terminal  tooth  of  the  front  tibite  of  some  Scaritini,  of  the  family 
CanibuUe. 

8th.  The  head  is  most  fnjqucntly  prolonged  in  front  of  the  eyes,  forming 
a  bei>k,  which  is  usually  narrower  tliau  the  front,  and  fre(iuently  very 
sleiuler.  A  llattcned  prolongation,  similar  to  a  beak,  occurs  in  some  genera 
of  Ciiciijidp,  PjjthidtK  and  UMemcvidue,  but  not  elsewhere  in  the  normal 
Coleo[)tera. 

Dth.  In  the  vast  majority  of  species  the  labrum  is  wanting;  in  some 
Scolytidic  it  is  feebly  develoi)ed.  bu'  is  present  in  normal  form  only  in 
Rhiti'iniiiccrida'  and  Anihribiihe. 

lOtli.  Except  in  RhinonuiceridiB  and  Anthribidat  tlie  jialpi  are  short  and 
rigid,  with  the  joints  diminishing  in  size;  in  those  families  they  are  slender 
and  flexilde,  as  in  normal  Coleo|)tera. 

1  lib.  In  those  genera  in  which  the  hind  tibiic  aretruncat(!  and  margined 
at  tip,  forming  u  surface  called  a  corbel,  this  surface  may  be  glabrous  or 
scaly.  In  normal  Coleoptera  they  are  always  glabrous,  and  in  lli/poccph- 
ahm  alone  they  are  densel}'  clothed  with  hair.* 

Vilh.  A  peculiar  ridge  on  the  inner  surface  of  the  elytra,  into  which  th(! 
asceniliiig  margin  of  the  metathoracic  e])imera  and  ventral  segments  fit, 
giving  great  firmness  and  solidity  to  the  hinder  part  of  the  body.     This

ridiio  is  rarely  wantinji;  .ami  is  represented  amonj^  nornuil  Coleoptcni,  so 
f'iir  as  I  have  examined,  only  in  eeriaiu  IhipreHtidiv. 

These  characlers  taken  collectively,  in  addition  to  tlie  two  fun<lamental 
defininjjj  chafaclers  first  mentioned,  indicate  a  profound  diHereneo  in  or- 
ganization, wliieli  isolates  the  Khynchophora  I'rom  ail  other  Cohsoptera. 
From  this  isolation  results  the  necessity  ol'  classifying  them  upon  oilier 
characters  than  those  which  arc  found  useful  in  defining  series  and  fami- 
lies in  the  normal  ('oleoi)tera.  TIk;  great  resemblance  in  general  ajipcar- 
ance  of  the  insects  of  this  type,  and  the  endeavor  to  consider  them  as  only 
a  family  in  the  whole  series  of  (^)leoptera,  lias  caused  the  characters  used  in 
this  memoir  to  be  either  undevvalued  or  overlooked.  I  believe,  how(!ver, 
that  when  attention  is  directed  to  them,  and  to  certain  other  characters, 
which  I  have  not  hadtinu;  to  fully  investigate,  the  arrangement  of  these  in- 
sects into  natural  groups  will  be  found  as  simple  and  intelligible  as  that  of 
the  normal  (.'oh.'oplera. 

Among  the  investigations  which  yet  remain  imperfect,  I  would  mention 
as  sjiecially  deserving  of  atteiuion,  the  stridulating  organs.  Then;  are  in 
some  genera  spaces  on  the  inner  surface  of  tlu!  elytra,  which  have  a  pearly 
lustre,  and  which  are  probably  capable,  by  friction  against  the  ascend- 
ing margin  of  the  ventral  segments,  of  producing  a  sound.  I  have;  men- 
tioned these  undcu'  the  genus  LinfroiiotKx,  of  the  Phi/tono/aini,  but  they  an! 
present  in  many  genera  of  other  trii)es,  and  in  fact,  the  Conotracheli  nud 
many  others  are  known  to  emit  a  siiueaking  sound. 

The  homologies  of  the  parts  of  the  head,  by  reason  of  which  the  front  por- 
tion becomes  extended  into  a  beak,  and  the  basal  pi(!cc  on  the  under  surface 
(which  separates  the  gular  sutures  in  normal  Coleoptera)  disappears,  are  also 
worthy  of  attention;  so  too  are  the  larvse,  with  the  view  of  discovering 
some  general  characters  in  which  they  differ  from  those  of  other  Coleojitera. 

A  more  careful  study  should  also  be  made  of  the  antcnnic  of  the  Htoh/- 
tidit,  by  speciuKiiis  mounted  in  Canada  balsam,  so  that  the  homologies  of 
the  joints  of  the  funiclc,  when  tli(!y  disappear  may  be  ascertained.  The 
subject,  as  treated  in  this  memoir,  is,  I  may  say,  barely  sketched,  and  will 
yield  to  others,  who  may  devote  labor  to  it.not  only  the  correction  of  erro:s 
I  have  made,  but  many  new  truths  and  generalizations  greater  in  value 
than  those  to  Avliich  I  have  attained. 

The  afTlnities  of  the  families  of  I{liynclio])hora  among  themselves,  and 
their  res(anblances  to  various  series  or  families  of  the  normal  Coleoptera 
remain  to  be  indicated. 

The  typical  llhynehophora,  Curculioniihr,  while  exhibiting  in  flu;  ill f- 
ferent  tribes  characters  which  are  nion;  individualized  and  combined  with 
special  structures  in  the  other  f  iinilies,  occupy  a  central  position  around 
which  the  latter  may  be  gnuipcd. 

The  llhinomaceriiUf,  liy  the  presence  of  a  labrum  and  flexible  paljii,  as 
well  as  by  the  general  form  of  body.and  11 -jointed,  nnn  genicidate  anienniu, 
indicate  a  res(!mblance  to  Ulnno!<iiiiiin,  &c,,  of  the  P(/thi(I(P.  T\  i  Ot.'o-

seusil)ly  into  the  CwrcuUonhlu'.  Tlie  last  named  family  through  the  Eri- 
rhinhu  is  aflUiated  with  the  BhyiicJu'tidm,  and  through  the  Barini  with  the 
CdUdicln'fliP  and  GonsoiiidiB. 

The  Ilylastea  group  of  the  Seolytiditt  shows  strong  affinities  Avitli  the  Cos- 
Honidie,  and  a  slight  reversion  towards  the  Cryptorhynchini  of  the  Curcu- 
lionidce. 

The  Brenthidie  arc  isolated,  and  indicate  a  relationship  which  is  neither 
of  atlinity  or  analogy,  but  rather  of  contemporaneous  origin  with  Jfypocvph- 
(ilidw,  BhysodidiV,  Cti.pendw,  and  perhaps  sf)ine  other  families  of  normal 
Colcoptera,  which  have  been  yet  imperfectly  stuitied.  Nevertheless,  by 
certain  abnormal  genera,  not  occurring  in  our  fauna,  they  exhibit  a  re- 
semblance in  some  characters  to  the  sub-family  Platypodidm  of  the  Scoly- 
tidie,  and  connect  both,  by  their  resemblances  with  the  ColydiidiB  of  the 
Clavicorn  series  of  normal  Coleoptora.* 

Some  of  the  Scolytidm  in  form  and  general  appearance  resemble  the  feebler 
groups  (ChoraguH,  &c.)  of  the  AiUhribidm,  but  the  characters  of  the  latter 
are  so  peculiar,  that  they  must  l)e  viewed  as  a  synthetic  type,  combining 
resemblances  to  very  diverse  series.  The  form  of  the  mentum,  if  I  have 
interpreted  it  correctly,  is  found  only  in  the  Adeiihaga  (Amphizoa),  while 
the  great  sexual  dilfcrences  in  the  length  of  the  antenuic  occur  only  in  the 
Cerainbycida:  The  well  developed  labrum,  filiform  flexible  palpi,  straight, 
ll-j(.)inted  anlei^nse,  and  epipleura'  indicate  a  higher  organization  than  is 
found  in  other  Khynchophora.  The  complete  consolidation,  without  su- 
tures, of  the  elements  of  the  under  surface  of  the  head  and  prothorax,  indi- 
cate a  progress  along  the  line  of  true  Ilhyncliophorous  development,  upon 
which  I  have  based  the  two  fundamental  defining  characters.  The  pro- 
gress in  this  instance  has  been  carried  so  far  as  to  cause  tlie  disappear- 
ance of  these  very  characters.  If  any  resem])lance  to  the  normal  Colcop- 
tera could  be  seen  to  replace  them,  the  Anthribida;  would  be  removed,  as 
has  been  done  witli  the  Bruchidw,  to  some  other  part  of  the  system.  But 
this  is  not  the  case,  and  they  must  remain,  therefore,  as  the  expression  of 
the  most  perfect  development  thus  far  attained  in  the  lllij'nchophorous 

tyi>e.t. 

The  classification  here  adopted  is  simply  that  set  forth  by  me  in  the

Sciences,  at  the  session  held  at  Washington,  April,  1874;  I  have,  however, 
left  out  the  families  BraehyceridiB,  Amyeteridce  and  Belida,  defined  in 
that  essay,  but  which  are  not  represented  in  our  fauna. 

There  are  three  series,  composed  of  eleven  families,  represented  in  Tem- 
perate and  Arctic  North  America,  which  may  he  diagnosed  as  follows  : 

I.  Abdomen  (^  9  alike  ;  pygidium  small,  elytra  without  lateral  fold  on 

inner  surface HAPLOO-ASTRA. 

Labrum  distinct,  mandibles  flat,  simple Rhinomaceridse. 

Lubrum  wanting  : 
Mandibles  flat,  toothed  on  outer  and  inner  edge  RhynchitidSB. 

"         stout,  pincer-shaped Attelabidse. 

II.  Abdomen  J^  9  dissimilar  ;  J^  with  an  additional  anal  segment ;  pygid- 

ium large  ;  elytra  with  acute  lateral  fold  on  in- 
ner surface ALLOGASTRA. 

A.  Antennae  with  annulated  or  solid  club. 
Tarsi  narrow,  setose. 

Gular  margin  prominent,  prosternum  exca- 
vated   Byrsopidse. 

Tarsi  dilated,  usually  with  a  brush  of  hair  beneath. 

Mandibles  with  deciduous  tip,  leaving  a  scar  Otiorhynchidse. 
Mandibles  without  scar,    usually  pincer- 
shaped Curculionidse. 

B.  Antennae  with  ten  or  eleven  distinct  joints Brenthidae. 

in.  Abdomen  (^  9  alike  ;  elytra  with  a  distinct  lateral  fold  on  the  inner 
surface HETEROGASTRA. 

A.  Pygidium  vertical  or  declivous  : 

Antenna;  geniculate,  clubbed  ;  labrum  want- 
ing ;  last  spiracle  covered  by  ventral  seg- 
ments    CalandridtB. 

Antenna;  straight ;  labrum  distinct ;  last  spir- 
acle not  covered  by  ventral  segments  ;  py- 
gidium deeply  notched  to  receive  sutural 
apex  of  elytra Anthribidae. 

B.  Pygidium  horizontal,  smaller  : 

Antenna;  geniculate,  clubbed  ;  terminal  edge 

of  last  ventral  segment  acute,  surrounding 

the  last  dorsal ;  tibia;  generally  compressed 

and  serrate ScolytidSB. 

Antenna;  straight,  with  annulated  club  ;  max- 

illse  very  large,  palpi  and  ligula  feeble Apionidse. 

Among  the  genera  and  species  described  in  the  present  memoir,  there 
will  doubtless  be  many  which,  with  more  extended  comparisons,  will  be 
found  identical  with  those  which  occur  in  other  regions.     It  will  be  a  just

criticism,  that  I  have  failed  to  identify  them  Avitli  tliose  already  in  the  books. 
In  explanation  of  this,  I  would  say  that  I  have  defined  the  tribes,  genera 
and  species,  in  many  instances,  bj'  characters,  which  have  been  unnoticed 
or  neglected  by  previous  investigators  ;  and  finding  that  quite  frequently, 
species,  liaving  a  strong  external  resemblance,  dijlcred  by  structural  charac- 
ters of  great  moment,  I  did  not  feel  'Aairanted  in  applying  to  them  names 
given  to  species,  whicii  agreed  with  them  in  tlio  outline,  vcstiture  and 
sculpture  of  the  larger  parts  of  the  body,  but  which  have  been  described 
from  other  zoological  districts.  It  will  be  easy,  by  the  aid  of  the  structural 
characters  which  I  have  given,  to  identify  my  species  with  the  types  exist- 
ing in  European  cabinets.  I  would  rather  that  those  I  have  named  would 
sink  into  synonymy,  than  that,  in  the  present  condition  of  science,  I  should 
appear  to  teach  false  ideas  regarding  geographical  distribution,  which,  when 
carefully  studied,  must  give  us  important  aid  in  attaining  a  knowledge  of 
the  causes  and  development  of  the  existing  order  of  things.

Head  prominent,  not  deflcxed,  ej'es  rounded  finely  granulated  ;  beak 
slender,  varying  somewhat  in  fonn  according  to  the  genus. 

Protliorax  truncate  before  and  behind,  convex,  prosternal  sutures  not 
visible,  coxal  cavities  rounded,  somewhat  transverse,  with  a  distinct  fissure 
at  the  outer  side  margin  :  distant  in  Pterocolus,  confluent  in  other  genera. 

Mesosternum  flat,  acute  behind  in  all  but  Pterocolus,  and  with  the  side 
pieces  normal  iu  form  and  diagonally  divided  ;  in  that  genus  they  are  tnm.s 
verse,  prominent,  apparently  undivided,  and  ascend  between  the  prothorax 
and  humend  angle  of  the  elytra,  suddenly  declivous  and  excavated  in  front 
for  the  protection  of  the  legs  ;  coxal  cavities  approximate,  except  in  Pten>- 
colus. 

Metasternum  rather  long,  with  narrow  side  pieces  ;  shorter  with  wide 
side  pieces  in  Pterocolus. 

Elytra  separately  rounded  behind,  exposing  the  pygidium  in  some  gencni ; 
conjointly  rounded,  and  covering  the  pygidium  in  others,  epiplcunc  dis- 
tinct ;  submarginal  fold  on  inner  face  short  and  straight. 

Abdomen  with  five  free  ventral  segments,  nearly  equal  in  length,  sepa- 
rated by  straight  sutures,  intercoxal  process  acute  except  in  Pterocolus  : 
(J*  without  additi(mal  anal  segment,  pygidium  in  both  sexes  triangular,  de- 
flcxed ;  sides  of  segments  not  forming  an  acute  edge,  and  not  fitting  into  a 
lateral  groove  of  the  elytra. 

Anterior  coxaj  usually  conical,  contiguous,  and  prominent ;  smaller, 
rounded  and  separated  in  Pterocolus. 

Middle  coxae  similar  to  the  front  ones. 

Hind  coxae  transverse,  reaching  to  the  margin  of  the  elytra,  or  nearly  so. 

Legs  slender,  rather  long,  tibiae  truncate  at  tip,  -with  small  terminal 
spurs  ;  tarsi  brush-like  beneath,  4-jointed,  third  joint  broad  deeply  bilobed ; 
claws  bifid,  or  acutely  toothed. 

Though  nearly  related  to  the  preceding  famih',  these  species  arc  readily 
distinguished  by  the  absence  of  labrum,  and  the  peculiar  form  of  mandible, 
which  recurs  again  only  in  Desmoris,  an  Erirhine  genus  of  Cureulionida?. 

While  in  RhinomaceridsB  a  relationship  to  nonnal  Ooleoptera  is  seen  in 
the  presence  of  a  labrum,  and  better  development  of  maxillary  palpi,  a

similiir  tendency  is  evinced  in  the  Illiyneliilidte  by  the  distinct  cpiplctirre. 
In  tl>c  anonialous  genus  Pterocolus  moreover,  tlic  prothomx  is  distinctly 
and  acutely  margined  at  the  sides,  and  excavated  beneatli,  so  ns  to  form  a 
large  cavity  for  the  reception  of  tlie  front  and  middle  legs.  This  character 
is  seen  in  no  other  Rhynchophorous  insect,  and  would  almost  warrant  its 
reception  as  a  distinct  family.  For  the  present  however,  I  prefer  placing 
it  as  a  sub-family. 

Subfamily  I.    KlIYNCHITIDiE. 

The  distinctive  characters  of  this  8ul)-family  have  been  irainted  out,  but 
may  be  briefly  resumed  as  follows  : 

Body  rather  elongate,  or  pyriform,  front  and  middle  coxse  contiguous, 
conical,  prominent.  Prothorax  without  side  margin,  not  excavated  be- 
neath. Mesotborax  with  side  pieces  diagonally  divided,  epimera  not  ascend- 
ing.    Metathorax  witli  narrow  parallel  .side  pieces. 

Our  genera  are  as  follows  : 

Pygidium  covered  by  elytra.

EUQNAMPTUS  Sch. 

The  species  of  this  genus  are  more  slender  in  form  than  the  other  mem- 
bers of  the  family,  and  the  legs  are  longer  and  more  feeble.  Acccjrding  lo 
the  punctuation  of  the  head,  prothorax  and  elytra,  the  Bpecles  may  be 
readily  recognized  : 

Elytral  interspaces  very  narrow 1.  striatus.

Of  twelve  specimens  before  me  all  seem  to  be  9,  and  differ  from  those 
of  the  preceding  siM'cies  only  by  having  the  head  behind  the  eyes  cylindri- 
cal and  not  narrowed.  It  may  possibly  be  a  dimorphous  form  of  Ku.

4.  Eu.  puncticeps,  n.  sp. 

Of  the  same  form  as  coll<irii>,  testaceous  clothed  with  erect  hairs.  Beak 
rather  stouter  less  deeply  sculptured,  front  obsoletely  channeled,  head 
coarsely  and  sparsely  punctured,  cylindrical  not  narrowed  behind.  Pro- 
thorax  coarsely  punctured,  feebly  channeled.  Elytra  with  striic  composed 
of  approximate  punctures,  interRpaces  wide  flat,  each  with  a  row  of  very 
small  distant  punctures.  Antennas  extending  to  the  base  of  prothorax, 
stoutfr  than  in  the  other  species.     Length  :5.(5  mm's;  .1.')  inch. 

Illinois,  Mr.  B.  D.  Walsh  ;  Georgia.  I  have  seen  but  two  $  of  this 
species  ;  it  is  easily  recognized  by  the  stouter  antenna;,  and  more  uni- 
formly sculptured  beak,  whicli  is  free  from  the  impressions  and  lines  seen 
in  the  two  preceding  species. 

5.  Eu.  sulcifrons  Gyll.,  Seh.  Cure,  v,  343. 

I  refer  to  this  species,  a  (J*  from  Texas,  sent  by  Mr.  Belfrage.  It  is  of 
exactly  the  same  form  and  sculpture  as  Eii.  tuirju^latu.^,  but  the  eyes  are 
less  prominent,  more  as  in  the  9  of  t'^'^t  species,  and  there  is  a  fine  but  dis- 
tinct frontal  channel ;  the  head  is  gradually  and  distinctly  narrowed  be- 
hind the  eyes.  The  color  is  testaceous,  with  a  lateral  blackish  viita  on  the 
elytra  gradually  becoming  broader  behind  ;  an  extension  of  this  dark  color 
would  give  the  appearance  mentioned  by  Gyllenhal,  in  whose  specimen 
the  elytra  were  blac''  with  a  blue  reflexion,  and  pale  piceous  towards  the 
base.

dilated  at  tip  ;  the  two  slrist  towards  the  base  are  equally  apparent,  and  the 
front  is  similarly  channeled.  The  head  and  prothorax  are  somewhat  less 
coarsely  punctured,  and  the  eljtral  stria;  are  more  evident,  and  composed 
of  rather  larger  punctures.  The  difl'erences,  except  in  color  and  form  of

perhaps,  sexual.

Sub-family  II.    PTEROCOLIDiE. 

A  single  species  constitutes  this  sub-family.  On  account  of  the  anomal- 
ous characters  its  place  in  the  series  of  Rlu'nchophora  has  been  changed  from 
time  to  time,  without  very  satisfactory  results.  The  latest  authoritj%  Lacor- 
daire,  deceived  by  the  broad  form  of  body,  and  ascending  side  pieces  of  the 
mesothorax  placed  it  in  the  neighborhood  of  Coutorhynchus.  A  study  of 
the  mouth  organs,  as  well  as  the  antennie,  shows  that  it  is  allied  to  Auletes 
and  Rhynchites,  while  the  other  differences  require  it  to  be  received  as  a 
very  peculiar  and  distinct  type. 

It  differs  from  the  genuine  Rhynchitida;  by  the  antenna;  inserted  much 
nearer  the  eyes,  which  are  suddenly  but  not  deeply  emarginate  in  front. 
The  side  margin  of  the  prothonix  is  acute  and  well  defined,  and  the  under 
surface,  with  the  anterior  part  of  the  mesothorax.  is  excavated,  forming  a 
large  cavity  for  the  reception  of  the  front  and  middle  legs.  The  elytra  are 
sculptured  with  wide  shallow  grooves,  which  are  confusedly  punctured  ; 
the  epipleuraj  are  distinct ;  the  tips  are  widely  dehiscent  and  separately 
rounded,  exix)sing  parts  of  three  dorsal  segments,  all  corneous  and  densely 
punctured  Front  and  middle  coxiE  small,  rounded,  widely  separated,  not 
j)ronunent ;  posterior  coxie  separated,  transverse,  intercoxal  process  broad. 
Tibiie  with  two  distinct  apical  spurs,  tarsi  dilated,  claws  appendiculate. 
Ventral  segments  short ;  pygidium  less  convex  in  the  ^f,  and  strongly  in- 
flexed.  Side  pieces  of  mesosternum  transverse,  solid,  ascending  between 
the  prothorax  and  elytra.     Side  pieces  of  metasternuni  wide.

The  species  of  this  genus  which  occur  in  our  fauna,  are  divided  by  Mr.

This  family  contains  but  a  small  number  of  genera,  all  confined  to  the 
Eastern  continent,  e.-cep'  ThecententiiH  which  is  restvicted  to  the  interior 
parts  of  the  United  States,  extending  i.ito  Texas  and  eastward  to  Illinois. 
It  forms  a  tribe  distinguished  from  other  Byrsopidiu  by  the  peculiar  con- 
forniation  of  the  prosternum,  which  forms  a  triangular  plate  in  front  of  the 
coxie. 

THECESTERNUS  Say. 

I  have  described  (Proc.  Acad.  Nat.  Sc,  1856,  18)  what  I  at  that  time 
believed  to  be  six  species  of  this  genus,  in  addition  to  the  one  described  by 
Say.  Subsequent  investigation  with  more  abundant  material  has  raised 
some  doubt  in  my  mind  as  to  the  validity  of  the  .specific  differences  which 
I  then  observed. 

It  is  quite  evideiil  that  tliere  are  several  species,  but  it  is  found  quite  im- 
possible to  define  them.  There  are  all  gradations  from  specimens  (  T.  huine- 
raliK)  in  which  the  humeral  processes  are  fully  one-third  as  long  as  the 
prothorax,  to  others  {T.  morbilloKUK)  in  which  the  elytra  are  truncate  at 
base,  and  the  humeral  angles  only  slightly  prolonged. 

It  may  be  regarded  therefore  us  a  genus  In  which  the  originally  distinct 
species  are  becoming  effaced  by  mixture. 

The  specimens  which  I  collected  in  Kansas   were  found  under  dried 

buftalodung.     I   have  since   received  several   individuals  from  Illinois, 

Texas,  and  Missouri ;  upon  one  of  the  latter  is  this  note,  made  by  Mr.  C. 

V.  Riley  :  "Cutting  off  blossoms  of  grapevines  in  May  ;  also  beaten  from 

Carya."

Famiiv  y.   otiorhy:n^chid^. 


Mentuin  variable,  sometimes  large,  filling  the  giilar  emarginatlon  and 
without  peduncle,  or  small  exposing  the  maxillce  and  ligula  and  with  dis- 
tinct peduncle. 

Labial  palpi  very  rarely  visible  and  then  very  short. 

Mandibles  short,  stout,  pincer-like,  verj-  rarely  slightly  scissor-like,  and 
in  one  instance  (Dirotogiuithus)  slightly'  laminiform  and  prominent.  Ante- 
rior face  with  a  distinct  scar  freciuentlj-  borne  at  the  tip  of  a  slight  process. 

Antenna*  inserted  at  the  sides  or  top  of  rostrum  always  in  front  of  middle 
and  usually  near  the  tip,  geniculate,  11-jointed  (except  in  Affraphns),  the 
last  three  forming  a  compact  club  with  distinct  evidences  of  the  sutures. 

He;ul  moderately  prominent,  nirely  {Af/dsphcerops)  deeply  inserted  ; 
beak  variable,  never  long  and  slender.  Scrobes  well  defined,  except  in 
OtiorhyneJdni,  and  receiving  the  first  joint  (scape)  of  the  antennte  in  repose. 

Prothorax  of  variable  form,  apex  usually  truncate;  rarely  slightly  pro- 
longed over  the  head,  base  truncate,  arcuate  or  bisinuate,  post  ocular  mar- 
gin either  truncate  or  with  ocular  lobe  more  or  less  developed,  sometimes 
with  stiff  fimbriae.     Anterior  coxtc  contiguous  (except  in  Payidelefejun). 

Mesosternum  short,  oblique  or  horizontal,  rarely  (Coleocci'U.i)  protuber- 
ant ;  middle  coxa;  narrowly  separated  ;  side  pieces  variable,  never  attaining 
the  coxal  cavity. 

Metasternum  variable,  short  in  Division  I,  usually  long  in  Division  II. 

Elytra  concealing  the  abdomen  entirely  from  above,  without  trace  of 
epipleuriE  but  with  inflexed  fold  on  their  inner  side. 

Abdomen  with  five  ventral  segments,  the  first  two  connate,  the  others 
free.     Intercoxal  process  variable. 

Legs  moderate  ;  femora  very  rarely  decidedly  clavate ;  tibia;  straight  or 
feebly  arcuate,  usually  mucronate  at  tip  and  rarely  with  small  spur-like 
processes  (certain  Oliorhynchi)u).  Claws  fixed  or  moveable,  always  simple, 
never  toothed. 

The  males  of  all  the  species  have  the  pygidium  divided,  so  that  there  are 
eight  doi"sal  segments,  while  in  the  female  there  are  but  seven. 

This  family  contains  all  those  genera  in  which  the  mandibles  arc  provided 
in  the  pupa  stage  with  a  deciduous  piece  of  varying  form,  usually  elongate 
and  slender,  sometimes  falcate  and  acute  or  short  and  conical.  In  the  early 
life  of  the  imago  these  pieces  are  lost  (although  specimens  occur  in  which 
one,  sometimes  both  are  preserved),  and  the  place  of  their  attachment  is  in- 
dicated by  a  scar  which  is  usually  on  the  face  of  the  mandible  but  frequently 
borne  at  the  tip  of  a  process  of  varying  length.  The  form  of  the  mandible 
itself  without  reference  to  the  scar,  indicates  the  occurrence  of  the  deciilu- 
ous  piece.  When  the  mandibles  arc  acute  at  lip  and  one  overlaps  the 
other  by  an  edge  more  or  less  acute,  no  deciduous  piece  ctm  be  expected. 
Its  occurrence  may  always  be  looked  for  in  those  in  which  the  mandibles 
meet  with  a  broad  surface  and  whose  function  is  rather  that  of  crushing 
than  cutting.    Bracfij/cerus,  Sttones,  Alophut  and  all  the  Mecorhynchi  are

instances  of  the  former,  while  Cyphu»,  Entimus,   Lepioj)s,    Ophryastex, 
Tanymecus,  etc.,  illustrate  the  latter  form. 

The  family  Otiorhynchidie  as  defined  by  Dr.  Leconte  (American  Natu- 
ralist, 1874,  p.  396),  has  but  little  to  do  with  the  tribe  of  the  same  name  as 
restricted  by  Lacordaire  (Genera  vi,  pp.  20  and  144),  as  it  includes  not 
only  the  greater  portion  of  the  Adelognathes,  but  also  several  tribes  of 
Phanerognathes  in  the  system  of  tlie  latter  author. 

In  examining  the  under  side  of  the  body  two  forms  of  construction  are 
found,  by  means  of  which  this  large  family  may  be  divided  into  two 
primary  sections. 

First.    Side  pieces  of  mesosternum  very  unequal,  the  episternum 
larger  and  attaining  the  elytral  margin,    epimeron  usually  small, 
sometimes  very  small.     Metasternal  side  pieces  never  very   wide, 
^,      generally  very  narrow  or  entirely  concealed  by  the  elytral  margin, 
\~     anterior  end  never  broadly  dilated  on  both  sides. 

Second.  Side  pieces  of  mesosternum  diagonally  divided  and  equal 
or  very  nearly  so,  episternum  distant  from  the  elytral  margin,  sepa- 
rated by  the  epimeron.  Metasternal  side  piece  moderately  wide, 
dilated  at  its  anterior  end  with  an  acute  process  of  greater  or  less  ex- 
tent projecting  inwards  between  the  mcsosternal  epimeron  and  the 
body  of  the  metasternum. 

The  accompanying  wood  cuts  have  been  drawn  natural  size  from 
(1)  Eupaffoderes  speciosus  Lee,  and  (2)  Hippoleptop»  tribalus  Fab., 
the  latter  from  a  specimen  kindly  sent  by  Mr.  H.  Jekel,  which 
although  foreign  (New  Holland),  was  of  sufBciently  large  size  to  allow  of 
the  drawing  being  made  natural  size.  In  the  cut  the  mcsosternal  epimeron 
is  left  entirely  black  that  its  position  as  well  as  the  form  of  the  adjacent 
parts,  might  be  rendered  more  evident. 

An  examination  of  the  foreign  genera  in  the  cabinet  of  the  Academy  of 
Nat.  Sc,  Phila.,  shows  that  the  use  of  the  above  characters  may  be  extend- 
ed to  genera  not  represented  in  our  fauna,  and  by  means  of  them  foreign 
genera,  evidently  allied,  may  be  brought  in  much  closer  proximitj'  than  by 
the  system  adopted  by  Lacordaire. 

No  genus  in  our  fauna  presents  any  extraordinary  or  anomalous  charac- 
ters. It  may  be  remarked  that  no  native  species  yet  known  is  provided 
with  any  femoral  armature,  and  all  our  genera  with  the  exception  of 
Agraphus  have  seven  joints  in  the  funicle  of  the  antennaj. 

By  reference  to  the  synoptic  tables,  the  extent  of  variation  in  other  por- 
tions of  the  body  may  be  ascertained. 

In  consequence  of  the  definition  of  the  present  family  by  the  presence  of 
the  mandibular  scar,  the  primary  characters  made  use  of  by  Lacordaire  sink 
into  even  less  than  secondary  importance,  and  as  we  have  in  the  tenehri- 
ONiD^  parallel  series  each  with  genera  of  maximum  and  minimum  develop- 
ment of  mentum,  so  we  have  in  the  RJiynchopliora  similar  parallels  in  the 
two  divisions  above  indicated. 

In  taking  the  structure  of  the  sternal  side-pieces  as  a  primary  means  of

dividing  this  family,  I  liave  found  tliat  genera  are  tlicrcby  approximated 
wliicli  are  now  widely  separated,  and  ot  which  the  best  authoriies  on  the 
subject  since  Lacordaire  acknowledge  the  affinities.  I  might  cite  Laptops 
and  Entimus  in  their  approximation  to  Vyphus  and  lihigut,  the  separation 
of  Brachy»tylua  from  the  Otiorhynchi  and  its  position  near  Cyphus  as  well  as 
Artipus  from  its  present  very  unnatural  position  to  a  place  near  Gyphua. 
The  character  is  therefore  suggested  as  a  better  method  of  subdivision, 
although  it  is  not  claimed  that  it  will  in  all  cases  be  found  infallible.  A 
very  limited  study  of  the  Rhynchophora  will  soon  produce  a  conviction 
that  there  is  on  the  one  hand  a  great  permanency  of  type  of  construction, 
and  when  variation  of  detail  does  occur,  it  is  so  gradual  as  to  leave  no 
abrupt  lines  of  division.

DIVISION    I. 

This  division  contains  those  genei-a  in  which  the  mesosternal  epimera  are 
small,  or  at  most  moderate,  the  episterna  in  contact  with  the  elytral  margin, 
the  metastemal  side-pieces  rarely  of  more  than  moderate  width  and  not 
dilated  at  anterior  end,  and  without  the  triangular  process  projecting 
between  the  mes-epimera  and  the  metasternum.  The  other  characters  of 
the  division  are  extremely  variable,  in  all,  however,  the  antennae  are  strongly 
geniculate.  All  the  genera  of  this  Division  in  our  fauna  have  a  large  men- 
tum  concealing  entirely  the  maxillfc,  excepting  in  the  last  tribe. 

The  following  tribes  are  represented  in  our  fauna : 
Thorax  without  ocular  lobes. 

Antennal  grooves    (scrobes)   lateral  directed 

inferiorly BBACHYDERINI. 

Antennal  grooves  short,  superior,  rarely  late- 
ral, and  then  directed  toward  the  eyes  UTiOKHYlVC'imvi. 

Thorax  with  ocular  lobes  more  or  less  distinct. 
Mentum  at  least  moderate,  concealing  in  great 
part  or  entirely  the  maxilla;.     Mandibles  ro- 
bust not  prominent,  scar  very  evident OPHRYASTIXI. 

Mentum  very  small,  maxillse  exposed,  mandi- 
bles prominent,   free  edge  rather  thin,  scar 

small,  very  narrow DiRorooNATHiKi. 

As  will  be  seen  by  the  above  table  the  presence  or  absence  of  ocular 
lobes  affords  the  only  means  of  separating  the  tribes  Brachyderini  and 
Ophrya»Uni,  and  the  character  must  be  strictly  interpreted.  The  latter 
tribe  has  the  ocular  lobes  sometimes  very  feeble  and  almost  wanting,  but 
as  the  lobes  disappear  the  flmbrise  become  more  evident.  In  the  former 
tribe  there  are  no  evidences  whatever  of  either  ocular  lobes  or  fimbria;.  In 
one  genus,  the  prosternum  is  more  emarginate  than  usual,  giving  an 
appearance  of  slight  ocular  lobes,  but  no  traces  whatever  of  flmbriee  are 
seen.  In  some  of  the  genera  of  Ophryastini,  the  metastemal  side  pieces 
become  of  moderate  width,  showing  somewhat  of  an  approximation  to  the

very  narrow  and  the  sutures  nearly  always  obliterated. 

Tribe  I.     bkachyderini. 

Rostrum  at  least  as  long  as  the  head  and  slightly  dilated  at  tip,  which  is 
more  or  less  emarginate.  Front  flat,  rarely  with  a  slight  deprosaion 
between  the  eyes.  Scrobes  moderately  deep,  usually  distinctly  limited  and 
very  oblique.  Antennie  moderate,  scape  attaining  the  eyes  rarely  (  Trigo- 
noscuta)  passing  them.  Thorax  without  ocular  lobes  or  fimbriie  and  not 
or  very  feebly  emarginate  beneath.  Scutellum  usually  distinct.  Elytra 
oval,  not  wider  than  the  thorax.  Mesosternal  epimeron  small,  episternum 
attaining  the  elytra.  Episternum  of  metasternum  narrow  suture  usually 
distinct  in  its  entire  length.  Abdomen  with  the  first  two  segments  (except 
in  Gr.  iv),  separated  by  an  arcuate  suture,  segments  3-4  short,  conjointly 
not  or  but  little  longer  than  the  second. 

As  thus  constituted,  the  tribe  is  widely  different  from  that  defined  by 
Lacordaire  under  the  same  name.  From  it  those  genera  have  been  re- 
moved in  which  the  mesosternal  side  pieces  are  diagonally  divided  and  the 
metasternal  episterna  moderately  wide  and  dilated  in  front.  These  form 
tribes  in  the  next  division.  It  is,  however,  extremely  difficult  to  fix  tribal 
limits  with  any  degree  of  certainty,  as  everj'  character  upon  which  classifi- 
cation has  been  baaed,  exhibits  a  degree  of  variability  almost  unparalleled 
in  any  other  series  of  Coleoptera.  The  ocular  lobes  of  the  thorax  especially 
exhibit  this  tendency,  and  the  pointed  outline  of  the  eye  which  usually 
accompanies  the  lobe  is  by  no  means  in  better  condition.  The  eye  may  be 
more  nearly  circular  in  outline  with  a  lobe  than  it  is  without  the  lobe. 

As  thus  constituted,  the  tribe  contains  the  following  groups  : 

Third  joint  of  all  the  tarsi  wider  than  the  second  and  deeply  bilobed. 
Tibia;  normal,  not  dilated  at  tip.     Scape  not  passing  the  eyes. 

Posterior  coxoe  small,  very  widely  separated 

Posterior  coxaj  normal  intercoxal  process  triangu- 
lar or  oval. 
Antennffi  scaly,  body  beneath  densely  scaly.    Elytra 

emarginate  at  base,  thorax  closely  applied 

Antennae  shining,    sparsely  hairy,  body  beneath 
nearly  naked. 

Tips  of  1  ind  tibioe  feebly  cavernous,  a  double  row 

of  spinules.     First  abdominal  suture  arcuate... 

Tips  of  hind  tibse  open,  a  single  row  of  spinules. 

First  abdominal  suture  straight  or  nearly  so  .. 

Anterior  tibite  dilated  at  tip  ;  scape  long,  passing  the

Group  I.     Mlny^-^eri. 

Rostrum  stout,  cylindrical,  as  long  as  the  head,  and  very  little  narrowed 
to  the  tip.  Scrobes  di'ip,  well  defined,  suddenly  arcuate  in  front,  gradually 
wider  behind  and  jjussing  beneath  the  eyes.  Mesosternal  side  pieces 
unequal.  Metasternal  episternum  linear,  suture  distinct.  Intercoxal  pro 
cess  very  broad  and  very  short.  Hind  coxte  very  small.  Corbels  of  hind 
tibia;  open,  tarsal  claws  free. 

The  form  of  the  head,  rostrum  and  scrobes  resembles  considerably  that  of 
Pandeletejus  of  the  Second  Division,  but  the  structure  of  the  sternal  side 
pieces  excludes  the  present  genus  from  anj^  such  association.  According  to 
the  system  adopted  by  Lacordaire,  this  genus  would  be  placed  in  the 
Brachyderides  vrais. 


MINYOMERUS  n.  g. 

Rostnnn  as  long  as  the    head,    continuous  with  it  and  but  slightly 
narrowed  toward  the  tip,  robust,  slightly  arcuate,  feebly  emarginate  at  tip. 
Head   feebly  transversely  impressed  behind  the  eyes,  which  are  small, 
round  and  coarseli^  granulated,  convex,  but  not  prominent,  scrobes  mode 
rately  well  defined,  deep  and  suddenly  flexed  in  front,  gradually  broader

gradually  clavate,  slightly  passing  the  middle  of  the  eye  ;  f\micle  7-jointed. 
first  two  joints  hmger,  the  first  longer  tlian  the  second  and  stouter,  3-7 
short  and  feeblj'  broader  externally  ;  club  elongate,  oval,  pointed.  Thorax 
cylindrical,  truncate  at  apex  and  base,  without  trace  of  ocular  lobes  or 
fluibriic.    Bcutellum  invisible.     Elytra  oblong  oval,  base  truncate  at  mi<ldle. 
humeri  broadly  rounded.     Middle  coxte  moderately  separated.     Mesostcr 
nal  r.ide  pieces  unequally  divided,  elytra  and  episterna  tontiguous.     Me- 
tasterral  episternum  very  narrow,  linear,  suture  distinct.     Metasternum 
short.       Posterior  coxie  small,   very   widely  distant.       Intercoxal  j)ro- 
cess  very  short.     Second  abdominal  segment  as  long  as  the  two  following 
united,  separated  from  the  first  by  a  suture  arcuate  at  miiidle.     Front  and 
middle  tibite  feebly  mucronate  at  tip,  corbels  of  hind  tibia;  open.     Tarsi 
with  coarse  hairs  beneath,  third  joint  feebly  bilobed.     Claws  free.     Bo<ly 
densely  scaly. 

The  feeble  transverse  impression  of  the  head  behind  the  eyes  is  a  charac- 
ter of  extremely  rare  occurrence,  which  is  found  also  in  Proictes,  8ch. 
Some  relationship  might  be  expected  between  the  two  genera.  I  have  not 
been  able  to  inspect  many  of  the  genera  belonging  to  the  group  Brachyde 
I'idea  vrais,  but  from  those  seen,  I  am  inclined  to  think  that  nearly  all 
should  be  referred  to  the  Second  Division  of  this  memoir. 

Two  species  are  known  to  me  : 

Thorax    slightly  broader    than    long,   sides    moderately 

arcuate innocuus. 

Thorax  as  long  as  wide,  slightly  narrower  behind languidus.

M.  languidus,  n.  sp. 

Form  elongate  oval,  surface  densely  covered  with  cinereous  scales.  Head 
and  rostrum  as  long  as  the  thorax.  Head  transversely  impressed  behind 
the  eyes.  Rostrum  feebly  emarginate  at  tip  and  with  slight  oval  smooth 
space,  surface  densely  scaly  and  with  few  short  scale-like  hairs.  Thorax 
slightly  longer  than  wide  cylindrical,  base  narrower  than  the  apex,  sides 
nearly  straight,  apex  and  base  truncate,  disc  regularly  convex,  coarsely, 
deeply  and  densely  punctured,  and  with  a  slight  median  line.  Elj'tra 
oblong  oval,  disc  obsoletely  striate,  striae  with  rather  large,  closely  placed 
punctures,  intervals  slightly  convex,  densely  scaly  and  each  with  a  single 
row  of  very  short  scale  like  hairs.  Body  beneath  and  legs  as  in  the  pre- 
ceding species.     Length  .14  inch  ;  3.5  mm. 

Two  specimens,  Arizona  and  Fort  Tejon,  Cal. 

In  both  species  the  deciduous  piece  has  left  a  very  inconspicuous  scar, 
transversely  oval  in  form  and  not  prominent  as  in  several  of  the  following 
groups.  I  have  not  seen  specimens  with  the  pieces  remaining.  The  men- 
turn  fills  completely  the  gular  emargination  which  is  nearly  semicircular  in 
form.  The  genae  are  notched  opposite  the  bases  of  the  mandibles.  The 
distance  between  the  posterior  coxae  is  equal  to  the  length  of  tJie  first  two 
abdominal  segments,  and  the  coxa;  are  not  larger  than  those  of  the  middle 
pair. 

Group  II.     Eplcnerl. 

The  species  composing  this  group  are  more  or  less  pyriform,  the  body 
above  and  beneath  densely  scaly,  the  elytra  of  a  pale-brownish  or  luteous 
color  with  the  tip  and  two  sinuous  bands  much  paler.  The  rostrum  is 
rather  stout,  usually  longer  than  the  head,  the  scrobes  deep,  well  defined, 

•  The  measurements  here  given  as  well  as  all  to  follow  in  the  present  paper, 
are  taken  from  the  apical  thoracic  margin  to  the  tip  of  the  elytra,  as  this  U 
more  certain  and  invariable  than  if  the  measurements  are  taken  from  the  tip 
of  the  beak,  which  varies  in  length.

and  rapidly  descending.    The  supports  of  tlie  deciduous  pieces  of  the  man 
dibles  are  moderately  or  very  prominent. 

The  genera  known  to  occur  in  our  fauna  may  be  recognised  by  tlie 
following  table  : 
Articular  face  of  hind  tibifc  glabrous,  supi)prt 
of  deciduous  piece  moderately  prominent. 
Antenna;  stout,  last  joint  of  funicle  short 
broad,  and  very  close  to  the  club.  Joints 

1-2  of  tarsi,  glabrous QRAPHORHINUS. 

Antenna;  more  slender,  joints  of  funicle 
conical,  the  last  distant  from  the  club. 

Tarsi  pubescent EPICiERUS. 

Articular  face  of  hind  tibia;  scaly.     Supjwrt 
of  deciduous  piece  very  prominent.   An- 

tennifi  rather  slender,  club  distinct ANOMADUS. 

The  deciduous  pieces  of  the  mandibles  are  shown  in  one  species  of 
Epiearus  They  are  falciform,  moderately  robust,  obtusely  pointed,  with 
the  upper  inner  side  concave,  smooth  and  shining. 

QRAPHORHINUS  Sch. 

Oraphorhinus  Schonhcrr,  Gen.   Cure,  i,  p.  510  ;  indicated  but  not  de 
scribed  by  Say. 

This  genus  has  all  the  essential  characters  of  Epiccerus,  and  diflFers  only 
in  the  following  particulars  : 

Antennre  shorter,  scape  slightly  clavate,  attaining  the  eyes,  funicle 
7-jointed,  first  two  joints  slightly  larger  than  the  others,  3-6  as  broad  as 
long,  the  seventh  broader  than  long,  and  In  close  proximity  to  the  club, 
the  latter  broadly  oval  and  pointed  at  tip.  Eyes  nearly  round,  slightly 
transverse.  Cotyloid  cavities  of  hind  tibia;  terminal  (coriejKes  ouvertei<) 
and  glabrous,  tarsi  beneath  glabrous  slightly  fimbriate  near  the  tips. 

Bj'  the  above  characters  it  will  be  seen  that  the  genus  difiers  from 
Epiemrus  in  the  form  of  the  antenna;,  the  form  of  the  i>osterior  cotyloid 
cavities  and  the  vestiture  of  the  tarsi.  The  species  below  being  the  type  of 
the  genus,  and  as  it  differs  in  several  particulars  from  the  Oraphorhinun  as 
described  by  Lacordaire  from  other  species,  these  should  constitute  another 
genus  differing  in  the  fonn  of  the  antennae  and  the  vestiture  of  the  tarsi.

Body  pyriform  robust.  Rostrum  robust,  quadrangular,  slightly  longer 
than  the  head,  tip  feebly  emarginate  and  with  a  smooth  triangular  space 
limited  behind  by  a  chevron-like  ridge  behind  which  is  a  groove,  above 
trisulcate  and  a  moderately  deep  transverse  impression  between  tlie  eyes, 
median  sulcus  broad,  lateral  sulci  short  but  deeper  ;  surface  densely  clotued 
with  cinereous  scales  andspai"sely  punctured.  Thorax  slightly  broader  at 
base  than  long,  sides  arcuate  converging  to  the  apex,  which  is  truncate.

One  specimen  from  the  south  of  Newfoundland  given  to  Dr.  LcConte 
by  M.  Putzeys,  of  Brussels.  The  specimen  is  nearly  entirely  deprived  of 
scales  and  black. 

Group  IV      iiormorl. 

Rostrum  longer  and  narrower  than  the  head,  subcylindrical  at  base, 
broader  at  tip,  alse  moderately  divergent,  apex  emarginate  and  with  a  V 
shaped  elevated  line,  median  line  distmctly  impres.sed.  Scrobes  deep  in 
front,  and  moderately  arcuate,  posteriorly  fecl>ly  marked  and  directed  be- 
neath {Ilormoru^)  or  toward  the  lower  border  of  the  eye  (Agasphcerops). 
AntenniB  moderately  long,  attaining  the  middle  of  the  eye  in  the  former 
and  barely  reaching  the  eye  in  the  latter.  Eyes  moderately  or  very  promi 
nent.  Metasternal  side  pieces  almost  entirely  concealed  by  the  elytra  ; 
metasternum  short.  Intercoxal  process  broad,  truncate,  second  abdominal 
segment  but  little  longer  than  the  third  and  separated  from  the  first  by  a 
straight  suture.     Corbels  of  hind  tibiae  open,  claws  of  tarsi  free. 

The  supports  of  the  deciduous  pieces  of  the  mandibles  are  very  promi- 
nent, obliquely  truncate  and  pointed  at  tip ;  the  deciduous  pieces  do  not 
exist  on  any  of  the  specimens  before  me.  The  open  posterior  corbels  and 
the  straight  first  abdominal  suture  would  seem  to  placj  the  two  genera  here 
included  in  Lacordaire's  Dlosyrides  with  which,  however,  they  have  but 
little  in  common. 

Two  genera  are  thus  separated  : 
Scape  attixining  the  middle  of  the  eyes,  the  latter 

moderately  prominent,  without  posterior  orbit.  HORMOBUS- 

Scape  barely  attaining  the  anterior  nargin  of  the 
eye,  the  latter  spherical,  prominent  and  with 
posterior  orbit AGASPH^ROPS. 

These  two  genera  have  the  elytra  at  base  feebly  emarginate  :md  some- 
what broader  than  the  thorax,  the  humeri  being  bn)adly  rounded  in  tlie 
latter  and  subrectangular  in  the  former  genus.  There  is  also  a  close  super- 
ficial resemblance  to  Otio.hyni'.huH,  especially  in  the  second,  where  the  sur- 
face is  black  and  with  few  and  inconspicuous  scales.  IIormoruK  is  how- 
ever more  ornate  as  will  be  seen  in  the  dcscriptio'i.  I  have  endeavored  to 
find  cenera  to  which  these  are  allied,  but  with  the  work  of  Lacordaire  and 
the  lin)ii''d  foreign  •olleclion  at  my  disposal  I  am  entirely  unable  to  do  so, 
I  must  then-fore  describe  them  so  far  as  to  make  tliem  recognizable  in  our 
faima  aud  leave  their  relationships  for  future  determination.

cription  given  bv  Motsclmlsky  is  so  extremely  vague  and  short  as  to  be 
entirely  valueless,  and  in  strict  justice  the  genus  should  be  credited  to 
Lacordaire. 

T.  pilosa  Motsch.  Etudes  Entom.  I,  1852,  p.  79 ;  Lacord.  Genera, 
Atlas  pi.  61,  fig.  5,  a-b. 

Form  oval,  robust,  surface  densely  covered  with  cinereous  scales  and 
moderately  long  greyisli  liairs  s^jarsely  placed,  elytra  irregularly  varie- 
gated with  fuscous.  Head  and  rostrum  as  long  the  tliorax,  densely  scaly 
and  sparsely  pilose.  Antennte  rufous,  hairy.  Thorax  broader  than  long, 
narrower  in  front,  sides  strongly  arcuate,  disc  convex,  surface  moderately 
densely  scaly.  Elytra  rather  broadly  oval,  humeri  broadly  rounded,  sides 
feebly  arcuate  and  slightly  acuminate  posteriorly,  disc  convex,  with  rows 
of  miidcrately  fine  punctures,  surfiice  dense'.y  scaly  and  sparsely  pilose. 
Body  beneath  moderately  densely  scaly  and  with  rather  longer  hairs  than  the 
upper  surface,  last  three  segments  of  abdomen  distinctly  pubescent.  Legs 
"  ore  sparsely  scaly  and  with  rather  long  greyish  haira.  Length  .23 — .36 
.  :';h;  5.5 — ^9  mm. 

Tlio  males  l;;ive  the  metivsternum  and  abdomen  broadly  concave.  The 
scales  covering  the  elytra  and,  in  fact,  the  entire  upper  surface  are  very 
variable  in  coloration.  The  ground  color  is  a  cinereous  usually  very  irregu- 
larly mottled  with  fuscous.  Occasionally  specimens  occur  in  which  the 
elytra  arc  pale  ochreous  with  an  irregular  band  on  the  middle  of  each  ely 
tron  becoming  gradually  broader  behind,  nearly  uniting  at  the  suture. 

This  species  is  not  rare  on  the  sea-coast  at  San  Francisco,  Cal. 

Group  V  l.     CalypttlU. 

Rostrum  not  longer  than  the  head,  sub-quadrangular,  very  slightly  nar- 
row ad  toward  the  tip  and  but  lit('3  narrower  than  the  head.  Eyes  lound, 
coarsely  granulated  and  almost  entirely  concealed  from  above  by  a  small 
tubercle.  Scrobes  lateral,  arcuate,  deep.  Thorax  without  ocular  lobes  or 
flmbrite.  Scutellum  very  indistinct.  Mesosternal  side  pieces  very  un- 
equal. Metasternum  short,  side  pieces  moderate,  suture  obliterated.  Ab- 
domen normal,  intercoxal  process  broad  truncate  in  front.  Tarsi  with 
coarse  spinous  hairs  beneath,  third  joint  not  wider  than  the  second  and 
feebly  emarginate,  last  joint  moderately  long,  claws  free.  Anterior  tibiaj 
feebly  mucronate  and  digitate  at  tip  with  four  or  five  coarse  spinules,  articu- 
lar ca'  'ties  of  hind  tibiie  cavernous. 

The  gular  emargination  is  moderately  large  and  without  sub -mental 
peduncle.  The  mentum  is  nearly  semicircular  in  shape  and  partially  ex- 
poses the  other  oral  organs,  the  maxilla)  being  slightly  visible  at  the  sides 
and  the  ligula  at  tip. 

The  combination  of  characters  above  given  will  be  found  very  difficult 
to  place  in  any  tribe  of  Lacordaire's  system.  The  genus  can  not  be  called 
Phanerognath,  as  the  mentum  conceals  the  greater  portion  of  the  oral  or- 
gans, and  I  am  equally  at  a  loss  for  a  iwsition  in  the  Adelognath  scries. 

The  occurrence  of  narrow  tarsi  in  this  portion  of  the  series  is  certainly

a  remarkable  circumstance  and  serves  to  illustrate  the  almost  utter  impossi 
bility  of  dividing  any  portion  of  the  Iliiynchophorus  sub-order  without 
apparently  doing  violence  to  some  imi)ortant  character.  As  the  present  is 
the  first  occurrence  of  this  character,  it  might  be  here  observed  that  two 
others  alwaj'S  accompany  it  (in  our  fauna)  viz. ; — The  appro.ximation  of  the 
last  joint  of  the  funicle  to  the  club  and  the  tarsi  more  or  less  spinous  be- 
neath. Ophri/astes,  Ithigopsis,  and  Cimboccra,  the  only  genera  of  Otio- 
rhynchidse  in  our  fauna  with  narrowed  tarsi,  all  have  the  other  two  char- 
acters. The  tarsi  may,  however,  be  more  or  less  spinous  in  other  genera, 
but  the  antennal  character  never  occurs  Avithout  narrowed  tarsi.

Tribe  IL     ophryastiki. 

This  tribe  as  here  interpreted,  corresponds  very  nearly  with  the  Leptops- 
idea  of  Lacordaire,  as  far  as  our  genera  arc  concerned.     Lacordaire  in

OTIORHYI«rCHID^.

eludes  very  heterogeneous  material  as  must  be  evident  to  even  a  superficial 
observer.  No  one  can  deny  the  necessity  of  approacliing  Entimux  and  its 
allies  to  Gyphm,  forming  a  distinct  tribe,  liowevcr,  from  the  latter,  and  at 
the  same  time  Zdp<07)«  must  be  similarly  dealt  with,  and  should  probably 
be  placed  with  the  Entimides.  As  far  as  I  have  studied  the  majority  of 
the  genera  of  the  group  Leptopsides  vrais,  should  remain  in  the  present 
tribe. 

As  Leptops  belongs  to  my  second  division,  I  have  been  compelled  to 
change  the  name  of  the  tribe,  and  have  adopted  that  of  our  most  prominent 
genus. 

As  interpreted  in  the  present  paper,  this  tribe  has  the  following  charac- 
teristics : 

Rostrum  moderately  or  very  robust,  quadrangular  or  sub-cylindrical. 
Mandibles  robust,  never  prominent  or  laminiform  at  tip,  scar  round,  very 
distinct  and  sometimes  prominent.  Mentum  large  or  at  least  moderate, 
concealing  in  great  part  the  otlier  oral  organs,  sub-mentum  rarely  feebly 
pedunculate.  Scrobes  lateral,  rarely  (Phi/xelis)  visil)lc  fronx  above,  di- 
rected either  toward  the  middle  of  the  eyes  or  inferiorly.  Antennie  mode- 
rate, scape  always  attaining  at  least  the  eye,  funicle  7-jointed,  the  last 
usually  free,  rarely  (Cimbocera  and  Ophryanteit)  contiguous  to  the  mass. 
Thorax  always  with  distinct  ocular  lobes  which  are  frequently  flml)riate. 
"M-ptasternum  usually  very  short,  side  pieces  usually  narrow,  suture  nearly 
ahvays  visible.  Mesosternal  side  pieces  unequally  divided,  episternum 
and  elytral  margin  contiguous.  Intercoxal  process  at  least  moderately, 
sometimes  very  broad  (RhigopsiK).  Abdomen  variable,  second  segment 
longer  than  the  two  following  united  (except  in  Ophryastes),  and  with  the 
first  suture  arcuate  (except  in  Ophryaates  and  some  Strangaliodea).  Tarsi 
variable,  usually  pubescent  beneath,  sometimes  spinous  ;  third  joint  usually 
deeply  bilobed  and  broader,  nirely  simply  emarginate  and  not  wider  than 
the  second,  (certain  Ophrymtea,  and  in  Gimbocera  and  Ehigopsin).  Claws 
always  free.     Body  always  ajjterous. 

The  tribe  contains  moderately  hon\ogeneous  material  but  with  evident 
tendencies  in  some  of  the  genera  to  closely  approximate  those  of  neighbor- 
ing tribes,  especiallj'  is  this  the  c^se  in  those  genera  with  the  feebler  ocular 
lobes.  Tiius  Phyxelis  approaches  Trachyphloeua  and  Phymatinns  to 
Otiorhynehwt.  There  is  very  little  tendency  to  approch  Division  II, 
Phymatinus  alone  having  the  mcsostern.il  side  pieces  nearly  equally  divided 
but  the  metasternal  parapleurie  are  not  at  all  like  those  of  that  division. 

The  genera  of  the  tribe  form  the  following  groups: 

Rostrum  robust,  quadrangular,  more  or  less  distinctly  trisulcate  above. 

Scrobes  rapidly  inferior,  well  defined.     Eyes  always  narrow  and  acute 

below,  partially  concealed  by  the  ocular  lobes. 
Abdomen  M'ith  second  segment  rarely  as  long 

as  the  two  following  together,  first  suture 

straight.      Intercoxal  process    moderately 

wide Ophrya«t«a.

The  groups  as  above  defined  are  very  distinctly  limited  in  our  fauna,  the 
last  group  alone  being  of  doubtful  value. 

In  this  tribe,  occur  genera  with  the  narrow  third  tarsal  joint,  which 
however,  is  not  of  the  form  seen  in  the  BynsopiD^.  This  character  will  be 
spoken  of  at  greater  length  in  the  genera  In  which  it  occurs. 

Group  I.  Ophryastcs. 

Rostrum  robust,  angular,  more  or  less  distinctly  trisulcate,   tip  feebly 
cmarginate  with  a  small  triangular  smooth  space.     Antenna;  moderately 
robust,  scaly,  scape  gradually  thicker,   nearly  attaining  the  eyes,  funicle 
7-jointed,  the  last  joint  contiguous  to  the  club  which  is  oval.  Scrobes  deep, 
passing  obliquely  downwards  in  "'ont  of  the  eyes.    Eyes  oval,  transverse, 
pointed  beneath.     Thorax  variable  in  form,  either  oval  or  transverse,  :nid 
with  callosities  at  the  sides.    Elytra  oval  or  oblong.     Scutellum  wnncing. 
Abdominal  sutures  straight,  second  segment  equal  to,  or  very  little  longer 
than,  the  third.     Tibiae  not  mucronate  at  tip.   Tarsi  variable.     Claws  free. 
The  articular  surfaces  at  the  tips  of  the  hind  tibiae  are  verj'  nearly  termi- 
nal and  in  great  part  scaly.    Lacordaire  calls  them   " cnrerneuse,"  hnt  I 
think  without  reason  (for  the  majority  of  the  species).    They  arc  cavernous 
in  some  Eupagoderea.     The  mesosternal  side  pieces  are  very  unequal,  the 
epimeron  being  very  small.  The  metathoracic  episternum  is  moderately 
broad  and  the  suture  more  or  less  distinct.    In  all  the  species  the  ophthal- 
mic lobes  are  of  moderate  size  and  fimbriate.      The  surface  of  the  body  is 
densely  scaly  and  without  anj'^  pubescence. 
Two  genera  appear  to  be  indicated  in  our  fauna. 
Tarsi  slender,  third  joint  not  wider  than  second, 
and  simply  enuirginate.     Sides  of  thorax  with 
tuberosities  more  or  less  marked.  Tips  of  tarsal 

joints  beneath  spiniform OPHRYASTES. 

Tarsi  dilated,  third  joint  usually  wider  than 
second  and  deeply  bilobed.  Thorax  oval 
without  tuberosities,  tarsi  beneath  not  spinous 

at  tip EUPAQODERES. 

In  the  first  genus  the  elytra  are  broadly  oval,  in  the  second  elongate 
oval.     In  the  latter  also,  the  legs  are  longer.

The  species  of  this  genus  as  restricted  by  the  preceding  table,  are  not 
numeroVis,  and  have  a  facies  at  once  distinguisliing  tlieni  from  the  follow- 
ing genus.  They  are  all  of  robust  form,  elytra  rather  broadly  oval  and 
the  surface  densely  scaly,  either  cinereous  or  whitish,  ornamented  with 
8trij)cs  or  spots  of  a  much  darker  color.  Considerable  variation  within 
specific  limits  is  found,  not  only  in  color  but  also  in  form.  All  the  species 
with  but  one  exception,  have  at  the  base  of  the  rostrum  a  distinctly  marked 
transverse  impression  and  the  vertex  thus  appears  convex.  Tlie  tenth 
elytral  stria  in  the  larger  species  is  very  distinct  at  its  basal  third,  and  as 
distant  from  the  ninth  as  the  latter  is  from  the  eighth,  at  middle  the  stria 
is  not  evident,  and  at  its  apiciU  third  very  close  to  the  ninth.  In  the  smaller 
species,  in  which  also  the  thoracic  tuberosities  are  very  feeble,  the  tenth 
stria  is  entirely  obliterated.  The  deciduous  mandibular  piece  is  moderately 
long,  acute  at  tip,  slightly  arcuate.  This  piece  when  cast  leaves  merely  a 
a  scar  without  any  process. 

In  accordance  with  the  characters  our  species  may  be  tabulated  in  the 
following  manner: 
Tenth  elytral  stria  distinct  at  basal  third.     Thoracic 

tuberosities  large 1 

Tenth    elytral    stria    almost    entirely    obliterated.

EUPAGODERES,  n.  g. 

This  genus  contains  those  species,  formerly  placed  in  Ophryastes,  with- 
out lateral  thoracic  tuberosities.  The  tarsi  are  more  dilated,  the  joints 
proportionately  shorter  and  the  third  more  distinctly  bilobed.  The  distal 
angles  are  not  produced  in  a  spiniform  process,  a  character  by  no  means 
constant,  however,  in  Ophyrastes.  In  this  genus  the  articular  cavities  of 
the  hind  tibia;  become  internal  and  the  tip  of  the  tibia  truncate,  showing 
an  oval  scaly  space.  The  transition  from  the  double  apical  fringe,  which 
is  usual,  to  the  truncate  tip  with  the  two  rows  of  fimbria'  surrounding  an 
oval  space  is  in  this  genus  so  gradual,  even  Avith  the  limited  number  of 
species,  that  it  seems  to  indicate  the  little  value  of  the  characters  drawn  by 
Lacordaire  from  " corbeillen  ourertes"  and  " corbeilles  cuverneuses."  The 
deciduous  mandibular  i)iece  is  similar  to  that  of  Ophryastes.  As  in  the 
latter  genus  some  species  have  the  rostrum  and  vertex  continuous,  the 
greater  number,  however,  have  a  siuuation  at  the  base  of  the  rostrum.  0.

Form  oval,  color  piceous  densely  covered  with  cupreou.s  scales  almost 
entirely  obscured  by  a  dark  brown  exudation.  Head  and  rostrum  as  long 
as  the  thorax,  llostrum  above  trisulcale,  tip  obliquely  truncate,  front 
slightly  concave  and  with  a  hood-like  tubercle  over  each  eye.  Tliorax 
broader  than  long,  sides  at  anterior  third  more  rapidly  narrowing,  posterior 
two-thiids  ''eebly  converging  to  the  baP",  surface  tuberculate  and  very

The  appearance  of  this  insect  is  that  of  a  miniature  Rhigus,  or  («f  some 
Leptopn.  Its  affinities  appear  to  be  rather  with  Ophrymtes  than  with  any 
other  genus.

Group  IIT.     Strangallodea. 

The  group  as  made  up  in  the  following  table  is  not  precisely  that  in- 
tended by  Lacordaire.  There  are  without  doubt  several  genem  which 
should  be  placed  in  his  Kreiniiides,  but  with  the  exception  of  Phi/xelis  I 
can  find  no  genus  presenting  such  marked  diflerenees  in  the  form  of  the 
scrobes  as  to  render  it  possible  to  draw  the  line  with  any  degree  of  accuracy 
between  those  generc  in  which  the  scrobes  are  strictly  lateral  and  those 
with  the  scrobes  arcuate  and  directed  inferiorly. 

The  arrangement  of  the  genera  in  the  folluwipg  table  exhibits  a  gradual 
transition  in  the  form  and  length  of  the  rostrum  from  Diehorenus  which 
approaches  most  nearly  Ophryanten  in  this  resnect  as  well  as  in  the  struc- 
ture of  the  scrobes  and  abdomen,  to  Phym<i,tiini»  with  a  long  rostrum 
almost  entirely  lateml  sciobes  and  normal  al)domen.  Cimhoceni  by  its 
narrower  tarsi  and  the  structure  of  the  antenna*  appv  -.ches  Oj)hryn*te»  in 
another  direction.  Melamomphm  resembles  almost  pn-cisely  Amomphim 
in  form. 

I  have  not  been  able  to  obtain  any  characters  from  the  form  of  the  corl)el8 
of  the  hind  tibim,  but  have  been  compelled  to  group  seven  genera  l)y  a 
character  almost  as  feeble,  the  presence  or  absence  of  mucro  at  the  tip  of 
the  hind  tibia.  Our  genera  exhibit  such  a  similarity  of  strufture  that  it 
is  almost  Imjiossiblo  to  define  their  limits  and  with  the  addition  of  new 
material  generic  definition  will  be  reduced  to  a  work  of  extreme  difticully.

Having  found  it  necessary  to  separate  the  species  of  Dydobm  to  form 
two  genera,  I  have  chosen  as  the  type  the  first  species  mentioned  (D.  Her/niit) 
especially  as  it  is  the  only  one  in  which  the  second  abdominal  segment  is 
rather  short,  and  the  first  suture  straight.  This  genus  must  be  j)laced  near 
Panscopus,  which  it  resembles  somewhat  in  form  but  is  rather  more  elon-

distinct,  the  rostrum  short  and  stout,  and  the  surface  scaly  without  setae. 
In  these  particulars  it  ditlers  fnmi  one  or  other  of  these  two  genera,  .and 
agrees  with  them  in  having  the  corbels  open.

Rostrum  slightly  longer  and  narrower  than  the  head,  sub-quadrangular, 
slightly  dilated  and  feebly  emarginate  at  tip,  separated  from  the  front  by  a 
distinct,  arcuate  impression.  Sab-mentum  with  a  distinct  peduncle,  not 
inflexed.  Scrobes  deep,  well  defined,  rather  suddenly  arcuate  and  passing 
near  the  lower  border  of  the  eye.  Eyes  round,  coarsely  granulated,  feebly 
prominent.  Antennae  moderately  long  ;  scape  gradually  clavate,  attaining 
nearly  the  middle  of  the  eye  ;  funicle  7-jointed,  1-2  longer,  the  first  longer 
than  the  second,  5-7  obconical,  gradually  shorter  ;  club  oval,  pointed. 
Thorax  cylindrical,  sides  feebly  arcuate,  apex  slightly  narrower  and  with

acuminate  posteriorly,  base  not  wider  than  the  thorax  and  broadly  emar- 
ginate, humeri  rounded.  Metasternum  moderate,  side  pieces  narrow,  suture 
distinct  in  its  entire  length.  Intercoxal  process  broad,  rounded  in  front ; 
second  segment  of  abdomen  much  longer  than  the  two  following  united,

posterior)   distinctlj'   but  feebly  mucronato.     Articular  surfaces  of  liinil 
tibia;  distinctly  cavernous.     Claws  moderate,  free. 

It  is  not  without  doubt  tliat  I  consider  the  genus  before  me  identical  with 
Mimeten.  The  thorax  is  provided,  in  well  preserved  specimens  with  the 
post-ocular  thoracic  finibriic  characteristic  of  the  Tanyviecide%  of  Lat-or- 
daire.  Tiiese  hairs  are  however  very  easily  removable,  and  it  is  possible  tliat 
Lacordaire  may  have  had  a  sjiecimen  before  him  similar  to  one  now  at  hand. 
The  present  species  has  been  submitted  to  Mr.  H.  Jekel,  who  agrees  with 
me  in  placing  it  near  Amoinphua  and  its  allies.  The  mandibles  have  no 
prominent  support  for  the  deciduous  piece.  In  addition  to  the  characters 
given  in  the  table,  this  genus  has  a  much  less  robust  rostrum  and  the  fmn- 
tal  impression  is  between  the  eyes  and  not  at  a  distance  in  front  as  in 
Oi'imodema.

This  genus  is  a  part  of  that  included  by  Dr.  Leconte  in  IJffilohus,  the 
generic  description  of  which  appears  to  have  been  made  from  D.  si'f/nisAnd 
A.  granicolU»  of  the  i)resent  genus.  I  have  retained  the  name  J)i/Hli>l)uit 
for  the  species  with  the  tirst  alulominal  suture  straight  as  this  (•hanict(;r  is 
the  most  im])urtant  and  striking  in  the  description.  Regarding  the  position 
the  genus  should  occupy  in  the  groups  indiciated  by  Lacordaire,  1  am  in 
some  doubt.  The  scrobes  are  lateral,  feebly  arcuate  anil  directed  toward 
the  lower  front  of  the  eye.  They  do  not  become  rapidly  inferior  as  in 
several  genera  already  noted,  and  are  but  slightly  less  arcuate  and  less  (l«^ 
fined  than  in  Pamcopus. 

For  the  present,  I  prefer  to  retain  Amnesia  in  the  present  group  as  one 
of  the  leads  toward  the  PhytoHcaphi  to  which  the  next  genus  probably 
belongs,  Nocheles  in  turn  being  a  lead  toward  the  Kremnini. 

I  consider  (Dynlohns)  granicollis  Lee.  the  type  of  the  genus. 

The  following  table  will  make  our  species  easily  known  : 

Hairs  of  the  surface,    especially   on   the   elytra,  very  short  and  incon- 
spicuous.    Humeri  rectangular,  ii:itcrior  tibise 
moderately  denticulate. 
Body  beneath  rather  sparsely  and  not  coarsely 

punctured granicoUis. 

Body  beneath  with  coarse  deep  punctures, 
denser  on  the  Intercoxal  process  ami  last  ven- 
tral segment decorata. 

Hairs  of  surface  very  distinct,  usually  ratlier  long. 
Humeri  rectangular,    anterior    tibiic    moderately 
denticulate. 

Surface  of  thorax  even,  not  granulate ursina. 

Surface  of  thorax  granulate,  each  gninule  punc- 
tured   rauca. 

Humeri  obliterated,  anterior  tibiae  feebly  dentic- 
ulate, surface  of  thorax  with  punctured  granules. 
Elytra  oval,  wider  at  middle  than  the  thorax, 
and  not  twice  as  long  as  wide. 
Thorax  not  narrowed  in  front,  granules  incon- 
spicuous, surface  densely  scaly  ;  elytra  witli 
cinereous  scales alternata.

its  widest  part  but  little  narrower  than  the  elytra.  The  alternation  of  eleva- 
tion of  the  intervals  is  very  little  marked  ou  the  disc  and  is  but  slightly 
more  evident  near  the  declivity.

A.  alternata,  n.  sp. 

Oblong  ovnl,  surface  densely  covered  with  brownish  cinereous  hairs,  the 
alternate  intervals  of  the  elytra  paler.  Head  and  rostrum  as  long  as  the 
thorax,  sparsely  punctured  and  with  erect  yellowish  hairs,  surface  densely 
covered  with  cinereous  scsiles,  brownish  at  the  sides  ;  rostrum  with  a  short 
median  impression  between  the  insertions  of  the  antennae.  Thorax  cylin- 
drical, veiy  slightly  broader  than  long,  sides  motlerately  arcuate,  .surface 
densely  covered  with  cinereous  scales,  si ightlj' clouded  at  middle,  with  few 
erect  L:  irs  ;  when  deprived  of  scales  the  surface  consists  of  flattened  punc- 
tured granules,  moderately  densely  placed.  Elytra  oblong  oval,  one-third

This  species  from  its  densely  scaly  surface  has  a  greater  superficial  re- 
semblance with  decoruta  than  the  sjK'cies  near  which  it  is  placed,  but  from 
its  having  nither  conspicuous  erect  hairs  on  the  entire  upper  surface  it 
must  be  placed  here.

saems  somciwhat  doubtful,  the  only  character  by  means  of  which  it  may  be

known  to  me,  as  experience  lias  already  shown  that  groups  of  genera  formed

basis  adopted  in  the  present  memoir  which  is  but  a  modification  and  ampli- 
fication of  that  suggested  by  Dr.  LeConte. 
One  genus  occurs  in  our  fauna. 

PHYXELIS  Sch. 

Phyxelis  Schiinh.  Cure,  vii,  1,  p.  123. 

nostrum  longer  and  somewhat  narrower  than  the  head,  slightly  arcuute, 
parallel,  sub-angular,  tip  slightly  emarginate  with  small  smooth  space 
limited  by  an  elevated  line.  Scrobes  visible  from  above,  moderately  deep 
badly  defined,  arcuate  and  not  attaining  the  eyes.  Antennte  mixlerate,  scape 
gradually  clavate  attaining  the  margin  of  the  thorax  ;  funicle  7-jointed,  1-2

lated. Thorax  broader  tlum  long,  sides  moderately  arcuate,  ocular  lobes 
feeble,  apex  and  base  truncate.  Scutellum  invisible.  Elytra  ra.her  broadly 
oval,  convex,  not  wider  at  base  than  the  thorax  and  feebly  emarginate, 
humeri  obtuse.  Metasternal  side  pieces  narrow  connate  without  distinct

nate,  posterior  corbels  open.  Tarsi  short,  stout,  fourth  joint  deeply  bilobed,

The  presence  of  thoracic  lobes  is  the  only  character  in  the  way  of  placing 
this  genus  near  Cercopeus.

Form  ovate,  piceous,  surface  moderately  densely  scaly  and  obscured  by 
a  luteous  exudation  coating.  Head  and  rostrum  longer  than  the  thorax, 
densely  scaly  and  sparsely  setigerous,  rostrum  at  base  with  more  or  less 
distinct  transveree  impression.  Thorax  somewhat  variable  in  form,  broader 
than  long,  sides  moderately  arcuate,  usually  narrowed  in  front,  base  feebly 
arcuate,  disc  convex,  median  line  more  or  less  impressed,  surface  densely

sub-recUingular,  disc  moderately  convex  indistinctly  striate,  intervals  feebly 
convex,  each  with  a  single  row  of  not  closely  placed  sub-erect  settc.  Body 
beneath  clothed  as  above,  legs  sparsely  setigerous.  Length  .14-.  20  inch  ; 
8.5-5  mm. 

The  color  of  the  coating  varies  very  greatly,  usually  pale  ochreous  some- 
times dark  brown,  and  it  adheres  so  closely  and  so  obscures  the  true  sculp- 
ture of  the  insect  as  to  render  it  almost  im{H)ssible  to  obtain  an  accurate 
idea  of  the  surface.  I  cannot  find  any  reason  for  distinguishing  three 
species  in  our  fauna. 

Occurs  from  Canada  to  Georgia.     Not  rare.

Tribe  II.   OTIORHYKOHI.%1. 


[Horn. 


Antonnaj  Ions,  scape  always  passinj;  the  eyes  behind.  Scrobes  variable 
but  never  at  the  same  time  linear  and  directed  interiorly.  MetaHternal  side 
pieces  usually  entirely  concealed  by  the  elytra,  rarely  of  moderate  width. 
Mesosternal  epimora  small.  Elytral  striie  entire  in  all  our  j^enera,  tenth  or 
marginal  always  distant  from  the  preceding  in  its  entire  length. 

It  is  extremely  difficult  to  give  characters  which  define  tril)es  of  Uhyn- 
cliophoni  with  any  degree  of  certainty,  and  it  is  frequently  found  that  a 
species  can  only  be  assigned  a  position  by  the  consideration  of  almost  its 
entire  structure  with  considerable  allowance  for  facies,  and  not  a  little,  by 
the  experience  of  the  student. 

Some  of  the  genera  placed  in  the  Otiorhj/nchini  by  Lacordaire,  have  been 
removed  and  will  constitute  portions  of  tribes  in  Division  ii,  with  wide 
metasternal  side  pieces. 

Our  genera  form  four  groups  which  may  be  distinguished  as  follows  : 
Funide  C-jointed  ;  articular  surface  of  hind  tibioj 
enclosed,    tips    of   hind   tibiic    truncate    with 

broad  oval  space 

Funlcle  Tjointed  ;  articular  sdrface   free,    tips  of 
hind  tibia'  with  a  single  row  of  fimbrite. 
Claws  free. 

Antenna' long  ;  outer  joints  of  funicle  long. 
Antenna;  shorter;  outer  joints  short  or  moni- 

liform i 

Claws  connate. 

An'ienntu  as  in  Otiorhynchi 

The  Pen'teliaTii  i)laced  after  the  Otiorhynchi  from  their  greater  similarity 
of  form  and  structure,  the  only  difference  between  the  two  tribes  is  found 
in  the  claws. 

Group  I.  Avrniihi. 

Antenna'  moderate,  scape  longer  than  the  funicle  and  club,  moderately 
arcuate  ;  funicle  (i-jointed  ;  club  broadly  oval  slightly  flattened,  composed 
in  great  part  of  the  first  joint  only,  the  other  joints  retracted  and  very,  in 
distinct.  Tarsi  long,  slender,  third  joint  very  feebly  emarginate  and 
scarcely  wider  than  the  second.  Hind  tibiie  truncate  at  tip  with  broad, 
oval  smooth  space,  cotyloid  cavities  internal.  Anterior  tibite  with  outer 
apica'  angle  slightly  prolonged  ;  anterior  and  middle  tibia'  with  innerangle 
mucronate. 

The  a\)o\  e  characters  appear  to  warrant  the  separation  of  Agraphits  as  a 
group  b}' itself  as  suggested  by  Lacordaire  who,  however,  failed  to  notice 
the  structure  of  the  antennal  club  and  placed  the  genus  in  a  groui)  in 
whicL  the  hinder  cotyloid  cavities  are  open.  These  latter  are  really  very 
strongly  cjivernous,  more  so  in  fact  than  in  any  other  genus  in  our  fauna. 

Agraphus  alone  constitutes  this  g'*oup.

near  the  tip  and  with  a  very  small  acute  tooth.     Length  .34  inch  ;  8.5  mm. 

This  species  has  been  so  often  described  in  easily  accessible  European 
publicUions,  that  I  consider  it  unnecessary  to  aild  to  the  above <lescription, 
this  with  the  table  being  sufficient  to  cnaldc  it  to  be  recognized  by  the 
student  of  our  fauna. 

Occurs  in  Massachusetts,  Canada,  Newfoundland  and  Nova  Scotia. 

O.  ligneus  Oliv.  Ent.  v,  83,  p.  378,  pi.  31,  fig.  473. 

Form  oblong,  color  piceous,  shining.  Rostrum  flat,  emarginate  at  tip. 
surface  very  coarsely  and  closely  jiunctured,  between  the  lyea  a  deep 
puncture.  Thorax  nearly  sidiericjil,  truncate  at  apex  and  lui'^e,  surface 
tuberculate,  (at  middle  the  tubercles  become  confluent  in  rows  with  deep 
sulci  between  them),  each  tubercle  punctured  at  summit  and  bearing  a 
short  hair.  Elytra  oval,  striate  at  the  sides,  striic  obsolete  on  the  di.sc  and 
'.vith  coarse  punctures  closely  placed,  intervals  flat  on  the  di.sc  and  feebly 
muricate,  at  sides  moderately  convex  and  slightly  tuberculate.  Legs  piceo 
rufous,  femora  clavate,  sinuate  near  the  tip  and  with  a  modenilely  strong 
tooth  bearing  a  denticle  on  its  free  edge.     Length  .20  inch  ;  5  mm. 

This  is  the  smallest  species  which  has  occurred  with  us,  and  may  be 
easily  known  by  the  femoral  armature  and  the  nearly  spheriad  thorax  with 
its  peculiar  sculpture. 

Occurs  in  the  New  England  States.

narrow  in  the  earlier  genera  (entirely  concealed  i)osti'riorly  in  Mw^k-m)

tooth-like  siiincs  around  the  apical  margin.     Claws  free. 

This  genus  dill'ers  by  very  marked  characters  from  those  wlii'-h  precede. 

In  the  latter  the  side  pieces  of  the  metasternum  are  entirely  concealed  by 
the  elytra.  In  this  the  eyes  are  surrounded  by  a  distinct  orbital  groove 
and  are  small,  scarcelj'  jtrominent  and  coarsely  granulated.  The  rather 
deep  transverse  impression  at  the  base  of  the  rostrum,  together  with  the 
convexity  of  the  rostrum  below  this  (owing  to  its  being  slightly  arcuate) 
give  this  insect  a  very  peculiar  fucies.

DIVISION    II. 

In  this  division  are  contained  all  those  genera  in  which  the  mesoslernal 
side  pieces  are  diagonally  divided  into  two  nearly  eipial  pieces,  the  outer  of 
whicli  (epimeron)  cuts  olf  the  inner  (episternum)  from  any  contact  with 
the  elytral  margin.  The  metasternal  episternum  is  usually  moderately 
broad,  the  suture  distinct  in  its  entire  length,  rarely  narrow,  and  in  one 
genus  tlie  suture  is  entirely  obliterated.  In  every  case,  however,  the 
anterior  end  of  the  metasternal  episternum  is  suddenly  dilated,  causing  on 
one  side  an  emargination  of  the  elytral  margin  (which  is,  however,  evan- 
escent), while  on  the  inner  side  an  acute  triangular  process  of  varying 
length  occupies  a  space  between  the  mesosternal  epimeron  and  the  body  of 
the  metasternum. 

The  antennal  scrobes  vary  in  form,  position  and  extent.  The  mentum 
is,  in  all  of  our  genera,  at  least  moderate  and  visible,  excei)ting  Eudingogus 
and  ColeoceniH  where  it  is  small  and  much  retracted,  allowing  the  parts  of 
the  mouth  to  be  visible.  The  beak  at  tip  exhibits  t,vo  distinct  forms.  In 
the  one  the  gena;  are  rather  deeply  notched  and  allow  the  base  of  the  man- 
dible to  be  exposed  ;  in  the  other  there  is  no  emargination  or  a  very  feeble 
one.  Accompanying  these  latter  characters  we  luvve  the  upper  portion  of 
the  beak  more  prolonged  over  the  mandibles  above  in  the  former  case, 


E.    ■

TANYMECIXI.

while  in  the  latter  the  mandibles  are  always  greatly  exposed  above.  A 
lateral  view  of  the  l)eak  will  therefore  show  the  tip  to  be  obliquely  trun- 
cate in  those  with  the  emari^inatc  gense,  and  squarely  truncate  in  the  other 
case. 

The  scar  of  the  deciduous  mandibular  cu.,p  is  very  distinct  in  all  the 
genera  e.vcepting  Coleoccrm,  and  is  usually  on  the  face  of  the  mandible, 
although  in  some  genera  at  the  summit  of  an  obtuse  process. 

The  tribes  forming  this  division  are  shown  in  the  following  table  : 

Mentum  moderate,  rarely  small,  never  retracted; 

sub-mentum  not  notched  at  middle  ;  tliora.x

GeniE  not  or  very  feebly  emarginate  ;  tenth

Rostrum  at  least  moderately  elongate, 
scrobes  long  ;  claws  free ;  head  not

surfaces  of  hind  tibitc  cavernous.  Men- 
tum large EXOPHTllAl<3fI9ir. 

Rostrum  rather  short,  scrobes  short ;  head

Mentum    small,    retracted ;    thorax   with   large 

ocular  lobes.     Eyes  transversely  oval PRONECOPI5iI. 

The  partial  obliteration  of  the  marginal  stria  occurs  in  but  one  tribe,  in 
the  others  that  stria  is  entire  and  nearly  equally  distant  from  the  pre- 
ceding throughout.  The  mentum  attains  the  minimum  in  the  last  two 
groups. 

Tribe  I.     TANYMECIJII. 

Rostrum  moderate,  sub-angulate,  sub-jiarallel,  more  or  less  emarginate 
at  tip  and  at  the  sides.  Scrobes  moderately  deep,  arcuate,  passing  beneath 
the  eyes.  Antenna;  moderate,  scape  moderately  long,  usually  attaining 
the  hind  margin  of  the  eye,  sometimes  attaining  the  thorax.  Thorax  with 
a,  short  row  of  bristly  l-.airs  behind  the  eyes  (and  in  PachiKvint  very  feebly

from  tlic  first  by  an  arcuate  suture.  Articular  cavities  of  hind  tibia 
varial)le.  Claws  free.  As  represented  in  our  fauna,  this  trilic  does  not 
dill'er  from  the  group  indicated  by  Lacordaire,  cxcei)t  in  the  addition  of 
Pundelctejm. 

Our  genera  are  as  follows  : 
Anterior  coxic  contiguous. 

Thoni.v   feebly  lobed    behind  the  eyes,    (the 
latter  transversely  oval,  pointed  beneath) 

and  bisinunte  at  liase 

Thorax  not  lobed,  base  truncate,   eyes  round, 

or  longitudinally  oval. 

Anterior  femora  normal,  the  tibiic  simple... 

Anterior  femora  much  longer  and  stouter 

than  the  others,  the  tibifc   denticulate 

Avithin 

Anterior  coxic  distant. 

Anterior  femora  larger  than  the  others.. 

The  articular  cavities  of  the  hind  tibise  vary  in  the  genera.  They  are 
feebly  enclosed  in  Pachnwiis,  more  decidedl}'  in  Tanymecm,  and  entirely 
open  in  the  other  two  genera.  Into  this  tribe  Polydacris  modestus  of 
Cuba  should  enter.  It  has  very  distinct  vibrissuj  composed  of  scales,  and 
the  anterior  coxrc  are  separated  as  in  Pamieletejus.  The  tribe  as  thus  con- 
stituted is  not  very  homogeneous,  and  with  more  genera  would  divide  into 
well  defined' groups,  each  of  the  above  genera  constituting  a  type.  With 
our  few  genera  this  appears  unnecessary.

Occurs  in  Florida,  and  Is  not  mre. 

The  ba.se  of  the  elytra  is  not  only  bisinuate,  but  there  is  also  a  small 
dentiform  prominence  contiguous  to  the  thoracic  hind  angles.  Lacordaire 
mentions  this  character  for  two  Cuban  species,  but  not  fur  our  own. 

P.  distans,  n.  sp. 

Form  elongate  oval,  den.sely  covered  with  pale  bluish  white  scales,  with 
faint  cupreous  lustre.  Head  and  rostrum  slightly  longer  than  the  thorax, 
densely  scaly.  Rostrum  with  a  fine  median  elevated  line,  ending  in  a 
frontal  puncture.  Thorax  broader  than  long,  slightly  narrower  in  front, 
sides  feebly  arcuate,  base  feebly  bisinuate,  di.sc  moderately  convex,  with 
large,  deep  punctures  irregularly  placed,  densely  scfily.  Scutellum  oval, 
truncate  at  base.  Elj'tra  oblong,  sides  feebly  arcuate,  base  very  feebly 
bisinuate,  humeri  not  dentiform  in  front,  convex,  densel}'  scaly  and  witli 
twelve  rows  of  coarse  and  moderately  deep  punctures,  intervals  tlat,  with 
a  single  row  of  minute  punctures,  each  bearing  a  longer  scale.  Body 
beneath  and  legs  densely  scaly,  and  with  minute  scale-like  hairs.  Length 
.32  inch  ;  8  mm. 

Notwithstanding  the  fact  that  the  elytra  are  not  prominent  at  the  middle 
of  the  base  of  each,  I  am  unwilling  to  separate  this  species  under  a  distinct 
generic  name.  In  the  generic  table  of  the  Tanymeciden,  Lacordaire  assigns 
strongly  cavernous  corbels  to  Pachmvus.  This  is  not  so  in  either  of  our 
species,  the  posterior  tibiie  having  at  their  tips  merely  the  double  row  of 
bristles  very  feebly  separated.  The  form  of  the  eyes  ai)pears  to  be  a 
character  of  greater  value  in  the  arrangement  of  the  genera  of  this  group, 
after  the  form  of  the  tarsi,  than  any  that  is  made  use  of  by  Lacordaire. 
Too  much  importance  seems  to  have  been  given  to  the  form  of  the  base  of 
the  elytra,  and  it  will  be  found  that  exceptions  are  met  with  frequently  in 
many  genera. 

The  species  above  described  was  collected  at  Cedar  Keys  and  Capron, 
Florida,  by  Messrs.  Schwartz  and  Hubbard.

Lacordaire  places  this  genus  among  the  Naupactides,  having  entirely 
overlooked  the  ftmbrite  at  tlie  side  of  the  thorax  behind  the  eyes.  No 
mention  is  made  of  the  separation  of  the  anterior  coxa;.  As  has  been 
already  mentioned  Polydccris  is  closely  related  to  Pandeleii.j..A ,  the 
anterior  coxic  arc  in  it  also  se[)arated,  and  the  sides  of  the  thorax  have  dis- 
tinct vibrissas  composed,  however,  of  scales.  I  think  tiiose  two  genera 
should  make  but  one. 

Two  species  occur  in  our  fauna  : 

Tip  of  ro.strum  entire,  without  smooth  space hilai'is. 

Tip  of  rostrum  emarginate,  with  smooth  space cinereus. 

These  two  differ  also  in  the  form  of  the  thorax.  In  the  latter,  the 
thorax  is  dilated  only  at  the  middle,  so  that  the  cylindrical  portions  in  front 
and  behind  the  dilatation  are  equal.  In  the  former,  the  dilatation  is  pyri- 
form,  and  the  anterior  narrower  part  much  shorter  than  the  posterior.

lateral  deep,  well-defined,  arcuate  and  passing  directly  beneath  the  eyes. 
Eyes  round,  moderately  prominent,  finely  granulated.  Antennse  moderate ; 
scape  feebly  clavate,  attaining  the  middle  of  the  eye  ;  funicle  7-jointed, 
joint  2  longer  than  the  first,  !}-7  sub-equal,  .slightly  obconical ;  club  elon- 
gate oval.  Thorax  broader  than  long,  narrower  in  front,  apex  truncate, 
base  bisinnate.  Scutellum  small  triangular.  Elytra  wider  at  base  than  the 
thorax,  humeri  moderately  prominent,  rather  more  than  twice  as  long  as 
wide,  and  at  apex  slightly  acuminate.  ]Metasternum  moderately  long.  In- 
tercoxal  process  broad,  sub-truncate.  Second  abdominal  segment  as  long 
as  the  two  following  united,  separated  from  the  first  by  a  feebly  arcuate 
suture.  Articular  surface  of  hind  til)iie  enclosed  (cavernous),  and  ascend- 
ing.    Anterior  and  middle  tibitu  feel)ly  mucronate.     Body  densely  scaly. 

The  middle  and  hind  tibiic  have  the  articular  surfaces  ascending  one- 
third  the  length  of  the  tibiiC,  the  edge  being  sharp  and  fimbriate  with 
bristly  hairs.  The  surfaces  are  however  entirely  glabrous.  In  addition  to 
the  dift'erences  in  the  number  of  the  dorsal  segments  of  the  sexes,  the 
females  may  be  known  by  an  additional  character.  On  each  side  of  the 
last  segment,  is  a  short,  rather  deeply-lmi)ressed  lino,  panillel  with  the  late- 
ral margin  and  about  one-fourth  the  width  of  the  segment  from  the  side, 
beginning  at  the  last  ventral  suture  and  extending  nearly  half  the  length 
of  the  segment.  The  last  ventral  of  the  male  is  not  so  marked,  and  is 
rather  longer  than  in  the  female. 

Two  species  occur  in  our  fauna. 

Thorax  abruptly  narrowed  in  front,  sides  behind  the  front 
angles  strongly  arcuate.  Anteriorly  rather  abruptly 
truncate lautus. 

Thorax  gradually  narrowed  from  base,  sides  feebly  arcuate. 
Apex  very  oblicpiely  truncate,  with  the  upper  margin 

decidedly  prolonged  over  the  occiput placidus. 

The  ditlerences  between  these  two  species  are  more  appreciable  in  nature 

than  expressible  by  words.     The  punctures  of  the  stritu  are  much  finer  in 

placidus  than  in  lautus.

Eljtra  oval  or  oblong,  not  wider  at  base  than  the  tliorax,  humeri  oblique, 
or  broadly  rounded.  Scutellum  distinct.  Antennre  long,  scape  passing  the 
eyes  behind.  Articular  surfaces  of  hind  tibiic  cavernous.  Rostrum  rather 
deeply  notched  behind  the  base  of  the  mandibles. 

The  essential  difterence  between  this  group  and  the  preceding  is  found 
in  the  form  of  the  elytra.  The  antennsB  (especially  the  scape),  are  longer 
and  more  slender.  The  rostrum  varies  in  form  and  is  usually  short,  stout, 
flattened  above  and  deeply  notched  at  tip.  In  one  genus  howcjver  the  ros- 
trum is  decidedly  Periteloid  with  less  divergent  alie.  All  the  genera  ex- 
cepting Artijnut  have  the  anterior  tibia)  denticulate  within. 

Our  genera  are  as  follows  : 
Rostrum  short,  s^out.     Scrobes  linear  in  front. 

Articular  surface  of  hind  tibiie  scaly  ;  anterior 

tibiie  not  denticulate  within ARTIPUS. 

Articular  surfaces  of  hind  tibire  glabrous  ;  ante- 
rior tibioo  more  or  less  denticulate  within.

On  examining  the  anterior  tibia;  with  ratlier  high  power,  minute  den- 
ticulations  may  be  detected.  T'.iis  species  resembles  one  from  Cuba  (sent 
by  Professor  Poey,  without  name)  which  has  tlie  elytral  intervals  more 
convex,  the  punctures  of  the  strite,  larger,  more  regular  and  closer  and  the 
thorax  more  densely  punctured. 

Several  specimens  from  Key  West,  Florida. 

ARAMIGUS  n.  g. 

Rostrum  slightly  narrower  than  the  head,  very  little  longer  and  some- 
what narrowed  in  front,  tip  triangularly  emarginatc,  gente  deci)ly  notched, 
base  of  mandibles  exposed,  above  finely  grooved.  Scrobes  lateral,  narrow 
in  front,  sides  slightly  divergent  behind,  arcuate  and  directed  beneath  ihc 
eyes.  ICyes  oval,  longitudinal  and  prominent.  Antenna;  sub-median, 
long,  slender ;  scape  hug,  slender,  rather  suddenly  clavatc,  attaining  the 
thorax  ;  funicle  7-jointed,  longer  than  the  scape,  joints  1-2  longer,  the  sec- 
ond much  longer  than  the  flrat,  joints  3-7  moderately  long,  sub-equal ; 
club  elongate  oval.  Thorax  cylindrical,  sides  feebly  arcuate.  Scutelhun 
either  small  or  indistinct.  Elytra  oval,  not  wider  than  the  thorax  and 
truncate  at  base.  Metasternum  moderate.  Intercoxal  process  of  abdomen 
broad,  truncate  ;  second  segment  of  abdomen  longer  than  the  two  follow- 
ing united,  separated  from  the  first  by  an  arcuate  suture.  Anterior  femora 
stouter  than  the  others,  their  tibia;  denticulate  within  and  mucronate  at  tip. 
Hind  tibiaj  with  the  posterior  edge  at  tip  acute,  margined  with  densely 
placed  spinulose  hairs.  Articular  cavities  not  or  extremely  feebly  cavern- 
ous and  ascending  the  tibia;.     Claws  moderate,  free.     Body  densely  scaly. 

This  genus  would  probablj'  belong  to  Lacordairc's  Brachyderides  and  its 
position  near  Eurijmetoinks.  The  resemblance  of  the  species  to  Strophoso- 
mus  has  already  been  noticed,  and  it  may  be  remarked  that  Eurymetopus 
has  also  been  so  compared.  I  lind,  however,  differences  of  sufhcicnt  im- 
portance in  the  descriptions  to  convince  me  that  our  species  cannot  be  re- 
ferred to  any  known  genus. 

Two  species  are  known  in  our  fauna  : 
Denticulation  of  anterior  tibiic  indistinct ;    surface  densely 

scaly tesselatus. 

Denticulation  very  distinct ;  surface  not  densely  covered .. .  Fulleri. 

The  humeri  of  the  first  species  are  rectangular  and  slightly  prominent 
anteriorly  and  in  the  latter  obliterated.  The  articular  surfaces  of  the  mid- 
dle tibiiB  ascend  nearly  as  much  as  in  the  hind  tibia;  in  tesselatus,  and  are 
not  at  all  ascendent  in  Fulleri.

densely  scaly,  tiblre  sparsely  pilose.     Length  .20-.30  inch  ;  5-7.5  ram. 

This  species  presents  two  varieties. 

var.  tesselattis  Say.  Head  and  rostrum  with  earthy -brown  scales,  paler 
around  the  eye  and  beneath.  Thorax  similar  in  color,  with  a  narrow  pale 
line  at  the  sides  and  a  broader  pale  line  on  each  side  of  a  brcud  median 
brownish  space.  Elytra  earthy-brown,  on  each  side  of  suture  obscurely 
variegated  with  paler  niottlings  and  a  small  pale  humeral  line,  and  a  narrow 
space  at  the  side  of  the  tip. 

These  specimens  are  found  in  Southern  Illinois. 

va}'.  pallidum.  This  variety  is  of  somewhat  larger  size  than  the  prece- 
ding, the  scales  covering  the  surface  are  pale-greenish  white,  and  witli 
barely  perceptible  darker  spaces  arranged  in  a  manner  similar  to  the  pre- 
ceding variety. 

This  variety  occurs  from  Kansas  to  Texas. 

Both  varieties  have  the  lateral  striaj  of  the  elytra  more  distinctly  im- 
pressed than  those  of  the  disc. 

A  specimen  of  tlie  latter  variety  was  submitted  to  Mr.  Pascoe,  who  was 
of  the  opinion  that  it  might  be  identical  with  "  Sitona  durius  Germ."  *

Head  and  rostrum  longer  than  the  thorax,  densely  punctured,  sparsely 
scaly,  nostrum  with  feeble  ridge  on  each  side  from  the  tip  nearly  to  the 
eyes.  Thorax  cylindrical,  apex  and  base  equal  and  truncate,  very  slightly 
wider  than  long,  sides  feebly  arcuate,  a  fine  median  line,  disc  moderately

"  Liparus  tesselatus  Say.  It  Is  a  Xmipacttts  sensu  Sch.,  so  very  allied  to  the

For  that  group  of  SVaupacti  I  have  created  the  genus  Aomopactus." 

I  am  not  aware  that  this  genus  suggested  by  Mr.  Jekel  has  been  described.

The  form  of  this  species  is  not  unlike  the  preceding.  The  elytra  arc, 
however,  narrower  between  the  humeri  and  the  thorax,  not  broader  at 
base. 

This  species  is  dedicated  to  my  friend  And,  S.  Fuller,  to  whom  I  am 
indebted  for  this  and  many  other  species. 

Occurs  from  New  Jersey  to  Montana. 

PHACEPHOLIS  n.   g. 

Rostrum  longer  than  the  head,  slightlj'  cuneiform,  sub-quadrangular, 
flattened  above,  and  with  a  fine  median  groove,  tip  triangularly  emarginate. 
Scrobcs  narrow,  moderately  deep,  well  defined,  slightly  broader  behind 
and  passing  immediately  beneath  the  eyes.  Eyes  round,  moderately 
prominent.  Antenna;  sub-median,  long,  slender ;  scape  nearly  attaining 
the  margin  of  the  thorax,  slender,  rather  suddenly  clavate  at  tip  ;  funicle 
7-jointed,  longer  than  the  scape,  joints  1-2  long,  the  second  much  longer  than 
the  first,  3-7  sub-equal,  7  obconical ;  club  elongate  oval.  Thorax  narrower 
in  front,  sides  moderately  arcuate,  base  truncate.  Scutcllum  triangular. 
Elytra  oval,  '"eebly  emarginate  at  base,  humeri  rounded.  Intercoxal  i)roce88 
of  abdomen  broad,  Ivuneatc  at  tip  ;  second  segment  longer  than  the  two  fol- 
lowing, separated  from  the  first  by  a  strongly  arcuate  suture.  Anterior 
tibiie  mucronate  at  tip,  rather  strongly  denticulate  within.  Iliud  tibise 
truncate  at  tip  with  oval,  densely  scaly  space,  articular  surfaces  cavernous, 
not  ascending,     Body  densely  scaly  and  pilose.     Claws  free. 

This  genus  resembles  the  preceding  in  form  and  ditfers  in  the  structure 
of  the  hind  tibim  and  the  more  distinct  scutellum.  The  mandibles  are 
moderately  prominent,  exposed  at  base  by  the  emargination  of  the  gense, 
their  surface  scaly.  The  supports  of  the  deciduous  pieces  are  prominent, 
and  obliquely  truncate.  The  deciduous  pieces  are  long,  slightly  curved 
and  glabrous.  I  cannot  satisfy  myself  that  this  genus  should  enter  any  of 
the  genera  proi)osed  by  Lacordaire. 

Three  species  occur  in  this  genus  which  differ  in  the  form  of  the  thorax 
as  follows  : 

Thorax  squarely  truncate  ;  eyes  not  prominent elegans. 

Thorax  obliquely  truncate  ;  eyes  prominent ;  head  slightly 

constricted  behuid  the  eyes obsoura. 

Thorax  obli(iuely  truncate  and  slightly  prolonged  over  the 

hsad  ;  eyes  feebly  prominent Candida. 

The  first  species  has  the  thorax  squarely  truncate,  so  that  it  is  no  longer 
on  the  dorsal  than  on  the  sternal  side.  The  eyes  arc  not  prominent,  and 
the  scales,  although  variable,  of  a  metallic  or  pearly  lustre.  In  the  second 
species  the  head  is  broadly  constricted  behind  the  eyes,  the  latter  promi- 
nent, and  the  thorax  is  obliciuelj'  truncate,  but  not  sub-lobed  in  front,  the 
scales  of  the  surface  are  luteous  without  lustre,  with  darker  spaces  on  the

thorax  and  elytra.  The  third  species  is  larger  than  the  other  two,  the 
scales  pale  cinereous  or  nearly  white.  The  thorax  is  obliquely  truncate 
and  somewhat  lobed  in  front  and  slightly  prolonged  over  the  occiput. 

P.  elegans,  n.  sp.* 

Oblong  oval,  moucrately  robust,  surface  densely  covered  witli  brilliant 
metallic  blue  scales,  varying  to  pearly  and  cupreous.  Head  and  rostrum 
as  long  as  the  thorax,  sparsely  punctured,  densely  scaly,  with  sparsely 
placed,  short,  erect  hairs,  median  line  finely  impressed.  Thorax  broader 
than  long,  slightly  narrower  in  front,  sides  feebly  arcuate,  apex  and  base 
truncate,  hind  angles  slightly  laminiform  ;  disc  moderately  convex,  mode- 
rately coarsely  punctured,  densely  covered  with  round  scales  and  with 
sparsely  placed,  very  short,  erect  hairs.  Elytra  oval,  slightly  acuminate 
posteriorly,  sides  feebly  arcuate,  sucface  striate,  stria  with  moderate  but 
not  closely  placed  punctures,  intervals  tlat,  densely  scaly,  and  with  two  or 
three  rows  of  short,  erect,  white  hairs.  Body  beneath  rather  sparsely 
scaly  and  setose.  Legs  sparsely  scaly,  tibire  sparsely'  hairy.  Length  .20- 
.28  inch  ;  fi-7  mm. 

The  thorax  at  base  is  very  feebly  bisinuate,  but  to  such  a  small  degree 
that  I  have  preferred  to  say  truncate.  The  vestiture  varies  in  color  greatly 
and  is  always  paler  beneath  than  above.  Resembles  considerably  the  figure 
given  by  Duval  of  Eunomus  ovulitm. 

Occurs  from  Kansas  to  Texas.  The  specimens  from  the  latter  region  are 
more  brilliant. 

P.  obscura,  n.  sp. 

Form  oval,  robust,  surface  densely  covered  with  .scales  and  short  erect 
hairs.  Head  and  rostrum  nearly  as  long  as  the  thorax,  head  feebly  con- 
stricted behind  the  eyes,  sparsely  punctured,  densely  covered  with  brown- 
ish scales,  above  each  eye  a  paler  space,  head  and  rostrum  beneath  nearly 
white.  Thorax  oval,  slightly  longer  than  wide  at  base,  apex  narrower  and 
obliquely  truncate,  sides  moderately  arcuate  and  gradually  converging  from 
base  to  apex  ;  disc  moderately  convex,  punctured,  median  line  feeble, 
densely  covered  with  brownish  scales,  a  broad  paler  line  on  each  side  of 
middle,  and  a  narrower  line  at  the  sides.  Elytra  regularly  oval,  scarcely 
attenuate  at  ai)ex,  disc  convex,  striate,  striaa  with  moderate,  not  closely 
placed  imnctures,  intervals  feeblj'^  convex  at  the  sides,  surface  densely 
covered  with  luteous  and  brownish  scales  in  irregular  longitudinal  stripes, 
each  interval  with  one  or  two  rows  of  moderately  long  erect  white  hairs. 
Body  beneath  and  legs  moderatelj'  densely  scaly  and  paler  than  the  upper 
surface.     Length  .22-.28  inch  ;  5.5-7  mm. 

This  species  has  much  more  the  aspect  of  Slrophosomus  than  any  other 
in  our  fauna.  The  eyes  arc  much  more  prominent  than  the  other  two 
species,  and  in  this  resembles  the  above  genus.

middle  tibite  denticulate  within  and  mucronate  at  tip,  more  strongly  in  the 
anterior.     Length  .32  inch  ;  8  mm. 

This  species  is  the  largest  of  the  three  at  present  known,  and  differs 
abundantly  from  either  of  those  just  described,  as  shown  in  the  synoptic 
table  and  the  remarks  following.

behind  the  mandibles,  above  with  a  fine  median  groove.  Head  very  slightly 
constricted  behind  the  eyes.  Scrobes  widely  open  from  above  ;  cavernous 
in  front,  very  shallow  posteriorly,  slightly  arcuate  and  directed  towards  the 
eyes.  Eyes  oval,  slightly  truncate  in  front  and  pointed  beneath.  An- 
tennas moderately  long,  slightly  scaly;  scape  feebly  clavate,  nearly  attain- 
ing the  thorax ;  funicle  not  longer  than  the  scape,  7-jointed ;  joints  1-2 
longer,  the  second  slightly  longer  than  the  first,  joints  3-7  slightlj'  obconi- 
cal,  sub-equal ;  club  oval.  Thorax  cylindrical,  narrower  in  front,  ui)ex 
obliquely  truncate,  base  very  slightly  arcuate.  Scutellum  moderate,  oval. 
El3'tra  oval,  base  moderately  emarginate,  humeri  oblique,  feebly  i)r(mii- 
nent.  Intercoxal  process  moderate,  oval  at  tip.  Second  segment  of  abdo- 
men longer  than  the  two  following  united,  separated  from  the  first  by  a 
strongly  arcuate  suture.  Anterior  and  middle  tibiie  feebly  mucronate  ;  ar- 
ticular surfaces  of  hind  tibia3  feebly  cavernous,  sparsely  scaly.  Claws  free. 
Body  densely  scaly. 

According  to  the  system  adopted  by  Lacordaire,  this  genus  belongs  to 
the  Emtylides  of  the  Otiorhyncliides.  The  construction  of  the  sternal  side 
pieces  excludes  it  at  once  from  the  latter  tribe.  The  scrobes,  and  in  fact  the 
structure  of  the  rostrum  generally,  are  very  nearly  that  of  Peritehm,  and 
its  appearance,  shape  and  coloration  do  not  differ  remarkably  from  P. 
grisetia  of  Europe.  I  prefer,  however,  to  place  the  genus  here  as  a  de- 
graded member  of  the  tribe  with  affinities  with  the  Otiorhynchini.     In-

other  tribes,  of  more  or  less  distant  position,  in  addition  to  tlic  distinctive 
cliiiracters  of  the  tribe  to  wiiicli  they  belong.  In  addition  to  the  above 
geiu!ric  characters  the  outer  elytral  striui  have  the  characteristic  form  of 
the  other  members  of  the  tribe,  the  outer  stria  joins  the  next  inner  one  third

A.  erriseus,  n.  sp. 

Form  oblong  oval,  gradually  narrower  anteriorlj',  surface  densely  cov- 
ered with'greyiah  scales,  irregularly  variegated  on  the  elytra  with  darker 
spots.  Head  and  rostrum  as  long  as  tlie  thorax  ;  a  fine  mecMum  line  extending 
to  tlic  vertex,  surface  moderately  densely  scaly.  Thorax  cylindrical,  some- 
what narrower  in  front,  sliglitly  longer  than  wide  ;  apex  truncate,  base 
feebly  arcuate,  sides  moderately  arcuate,  disc  convex,  moderately  denselj', 
but  not  coarsely,  punctured.  Elytra  oval,  one  and  a  half  times  longer  than 
wide,  conjointly  emarginate,  humeri  oblique,  feebly  prominent,  sides 
moderately  arcuate  and  gradually  divergent,  apex  feebly  prolonged  ;  disc 
moderately  convex,  feebly  striate,  striie  with  moilerate,  not  closely  placed 
punctures,  intervals  feebly  convex,  surface  densely  scaly,  each  interval 
with  a  single  row  of  minute  sctie.  Body  beneath  and  legs  densely  scaly, 
and  sparsel}'  setose.  Anterior  tibice  with  distant  denticulations  within  ;  at 
tip  (also  the  middle  tibiie)  finely  mucronate.  Length  .20-.24inch  ;  5-6  mm. 

In  many  of  the  specimens  the  intervals  slightly  alternate  in  the  degree  of 
their  convexity. 

Occurs  in  Texas. 

Group  III.     Aphrastl. 

Head  broader  behind  the  eyes  ;  scrobcs  slightly  visible  from  above,  deep, 
directed  toward  the  eyes  but  not  reaching  them,  gradually  broader  behind. 
Antennte  moderate.  Elj'tra  slightly  wider  at  base  than  the  thorax,  humeri 
obtuse.  Scutellum  distinct.  Articular  surface  of  hind  tibiie  not  cavernous, 
slightly  scaly.     Claws  connate. 

The  structure  of  the  tr  rsal  claws  will  serve  to  distinguish  this  group 
from  either  of  the  preceding.  The  outer  stria  of  the  elytrajoins  the  next 
inner  at  one-third  from  the  base  as  in  all  the  Cyphini  and  the  genaj  are 
deeply  emarginate. 

One  genus  constitutes  this  group  in  our  fauna.

The  second  joint  of  the  funicle  varies  in  the  two  species.  It  is  slightly 
longer  than  the  first  in  tteniatiis  and  shorter  in  iinkolor.  Lacordaire  is  in 
error  in  stating  that  the  second  joint  is  twice  the  length  ol  ihc  first  in  tanintus. 

Our  species  are  two  in  number.

9,  witliout  description. 

Head  and  rostrum  shorter  than  the  thorax,  densely  scaly  except  at  tip  ; 
scales  pale  brown  above,  cinereous  at  the  sides  and  beneath,  and  with 
sparsely  placed  short  erect  hairs.  Thorax  cylindrical,  slightly  luirrowed  in 
front,  sides  feebly  arcuate,  base  squarely,  apex  oblicpiely  truncate,  disc 
moderately  convex,  not  dcnselj'  punctured,  densely  scaly  ;  scales  pale 
brown  ;  a  pale  line  on  each  side  of  middle,  sides  and  beneath  cinereous. 
Elytra  oval,  feebly  striate,  striic  with  moderately  coarse  very  regularlj' 
placed  punctures,  intervals  feebly  convex,  surface  densely  clot  lied  with  cin- 
ereous scales ;  the  second  and  fourth  intervals  with  brownish  scales,  the 
inner  stripe  longer,  each  interval  with  a  row  of  very  short  whitish  hairs. 
Body  beneath  and  legsdensely  covered  with  cinereous  scales  ;  tibitu  sparsely 
hirsute.     Length  .20-. 23  inch  ;  5-  5.5  mm. 

This  insect  is  very  well-known  to  most  collectors.  The  species  has 
usually  been  attributed  to  Say,  but  as  the  description  of  Gyllenhal  is  really 
the  first,  it  appears  just  to  so  accredit  it. 

Occurs  in  the  Middle  and  Southern  States. 

A.  unicolor,  n.  sp. 

Form  elongate  oval,  densely  covered  with  cinereous  scales.  Head  and 
rostrum  as  long  as  the  thorax,  moderately  densely  scaly.  Thorax  regularly 
cylindrical,  sides  scarcely  arcuate,  apex  obliquely,  base  squarely  truncate, 
disc  sparsely  punctured,  surface  densely  scaly  and  with  whitish  erect  hairs. 
Elytra  oblong  oval,  feebly  striate,  stria;  with  large  rather  coarse  punctures 
very  regularly  placed,  intervals  feebly  convex,  densely  scaly,  each  with  a 
single  row  of  short,  white,  erect  hairs.  Body  beneath,  especially  the  abdo- 
men sparsely  scaly.  Legs  moderately  scaly,  tibia;  sparsely  pilose.  Length 
.18  inch  ;  4.5  mm. 

This  species  is  rather  narrower  than  taniatus  ;  thorax  more  regularly 
cylindrical,  and  with  the  erect  hairs  more  distinctly  visible.  It  difters  es- 
pecially in  the  structure  of  the  funicle  ;  the  second  j,oin.t  being  but  little 
more  than  half  the  length  of  the  first.

This  tribe  is  constructed  at  the  expense  of  the  Cyphides  as  defined  by 
Laeordaire.  It  contains  those  genera  in  which  the  rostrum  is  elongate, 
the  tenth  stria  entire,  and  the  gente  not  or  very  feebly  einarginate.  As  thu.q 
defined,  it  will  probal)ly  contain  all  of  the  last  six  genera  of  the  C'yphides. 
In  examining  a  series  of  Cid)an  species  i)resented  by  Prof.  Poey  to  the 
American  Entomological  Society,  I  find  the  specimens  of  Exophtlutlmua 
Sommeri  having  tlie  fimbriie  at  the  sides  of  the  thorax  as  strongly  marked

The  following  groups  may  be  recognized. 
Submentum  not  pedunculate  ;  mentum  broad.

The  differences  between  this  group  and  the  preceding  are  feeble,  and

This  genus  lias  been  defined  at  greater  length  than  has  been  the  custom 
in  this  paper,  on  account  of  the  very  remarkable  assemblage  of  characters

be  suspected  to  have  some  affinity  with  the  genera  allied  to  Alophua,  etc.

The  above  characters  serve  to  isolate  a  number  of  genera  evidently 
closely  allied  among  themselves,  and  also  with  well  marked  affinity  with 
certain  members  of  the  tribe  Gyphini.  The  mandibular  scar  is  not  promi-

mandible  itself.  The  deciduous  piece  is  modemtely  long,  glabrous  and 
regularly  falciform.  The  mentum  vaiies  in  size  in  the  genera  of  this 
group,  but  not  to  the  extent  of  causing  Scythropua  and  Phyllohius  to  be 
widely  separated. 

The  following  genera  compose  this  tribe  in  our  fauna  : 

Elytra  wider  at  base  than  the  thorax. 

Mentum  entirely  concealing  the  maxillae PHYLLOBIUS. 

Mentum  smaller,  maxillae  visible  at  the  sides. 
Rostrum  slightly  narrower  than  the  head  ; 

alaj  slightly  divergent CYPHOMIMUS. 

nostrum  short,  stout  ;  ahe  not  divergent SOYTHROPUS. 

Elytra  elongate,  oval,  as  narrow  at  base  as  the 
thorax. 

Mentum  small,  maxilla;  entirely  exposed MITOSTYLTJS. 

In  Mitontylus  the  sub-mentum  is  very  slightly  pedunculate.  Seythropus 
has  the  gula  semicircularly  emarginate,  and  the  maxillae  visible  at  the  sides 
of  the  mentum,  the  other  three  genera  have  the  gular  notch  nearly  square. 
lu  the  genera  2  and  4  the  mentum  is  very  narrow  and  the  other  parts  of 
the  mouth  very  distinctly  visible. 

PHYLLOBIUS  Germ. 

Phyllohiux  Germ.  Ins.  Spec.  nov.  p.  447. 

Rostrum  as  long  as  the  head  and  somewhat  narrower,  feebly  dilated  and 
slightly  emarginate  at  tip.  Scrobes  in  the  form  of  fossets,  sub-terminal. 
Eyes  oval,  slightly  oblique,  moderately  prominent.  Antenna;  long  and 
slender  ;  scape  slender,  feebly  clavate,  attaining  the  margin  of  the  thorax, 
funicle  7  jointed,  1-3  longer,  the  second  slightly  longer  than  the  first,  3-7 
sub-equal,  obconical;  club  elongate  oval.  Thorax  oval  broader  than  long. 
Scutellum  distinct.  Elytnv  broader  at  base  than  the  thorax,  humeri 
moderately  prominent,  oblong.  Intercoxal  process  oval.  Second  segment 
not  as  long  as  the  two  following  united,  separated  from  the  first  by  a  suture 
nearly  straight.  Femora  clavate,  the  anterior  more  strongl}'-.  Anteriorand 
middle  tibiie  mucronate,  articular  surfaces  of  hind  tibite  strictly  terminal. 
(Maws  connate.     Body  densely  scaly. 

One  species  is  known  to  me  in  our  fauna  which  may  be  merely  acciden- 
tal in  its  occurrence  as  I  have  aoen  but  one  specimen.

The  Catalogus  of  Gemminger  and  Harold  gives  glaucus  Scop,  as  an

I  adopt  tlic  name  used  by  English  entomologists,  leaving  bibliography  to 
those  more  intimately  concerned. 

CYPHOMIMUS  n.  g.

aloe  slightly  divergent,  gcmc  not  emarginate,  tip  feebly  notched.  Head 
moderately  prolonged  behind  the  eyes.  Scrobes  cavernous  in  front,

Tibiffi  not  mucronate,  articular  surface  of  hind  tibite  terminal,  glabrous. 
Claws  connate  at  base.     Marginal  elytral  stria  free. 

In  form  and  general  appearance  the  only  species  composing  the  genus 
resembles  BrachyHtylus  acutiis  but  with  a  longer  head  and  i-ostium.

short,  badly  limited  and  slightly  arcuate.  Eyes  distant  from  the  thorax, 
round,  slightly  prominent.  Antenna  long,  scape  long,  slender,  gradually 
clavate,  sliglitly  arcuate  and  passing  the  eyes  behind  ;  funiclo  7-jointed, 
1-3  L>nger.  the  first  slightly  longer  than  the  second,  3-7  shorter,  gradually 
decreasing ;  club  elon;jate,  oval.  1  horax  short,  cylindrical,  slightly

connate  at  base.     Body  densely  scaly. 

In  addition  to  the  above  characters  it  will  be  seen  that  the  gular  notch  is 
semicircular,  the  mentum  small  and  rather  narrow.  The  mandibles  are 
short,  robust,  glabrous,  the  scar  oval,  terminal  and  not  prominent.  The 
deciduous  pieces  are  long,  moderately  stout  and  falciform. 

Two  species  occur  in  our  fauna.  In  one,  elegam,  the  anterior  and  midf^'e

tibiiE  are  scarcely  perceptibly  sinuate.  The  vestiture  also  varies  and  may 
be  thus  expressed : 

Body  densely  covered  with  scales  of  variable  color 

from  brilliant  green  to  cinereous,  suture  always,

The  color  of  the  scales  is  very  variable  and  may  be  iivthcr  brilliant  green, 
slightly  cupreous,  plumbeous  or  cinereous.  Usually  the  sides  of  the  elytra

This  insect  has  been  mentioned  by  Dr.  Lecoate  (Amer.  Nat.   1874,  p. 
457)  as  being  probably  a  Macrosti/lua. 
Occurs  in  Texas. 

Tribe  V.     PRO.llE€OPl?II. 

Rostrum  short,  stout,  dilated,  (Coleocerus)  or  not  (Eudiaffogus)  in  front, 
tip  emarginate.  Antenna;  moderate,  scape  passing  the  eyes  or  not,  funicle 
7-jointed;  club  oval.  Scrobes  deep,  arcuate,  confluent  or  not  beneath. 
Thorax  with  large  lateral  lobes  and  deeply  emarginatc  beneath.  Sculellum 
distinct.  Abdomen  normal.  Tibia;  feebly  mucronate.  Tarsal  claws 
free. 

This  tribe,  corresponding  with  that  of  Lacordaire,  may  be  considered 
the  most  sharply  defined  and  natural  of  the  division.  Its  small  and  re- 
tracted mciitum,  large  thoracic  lobes  and  the  deep  emargination  of  the 
front  of  the  thorax  beneath,  at  once  distinguish  it.  As  in  the  preceding 
tribe  the  genie  are  entire  and  the  muulibles  covered  at  base. 

The  following  arc  the  genera  in  our  fauna: 

Rostrum  strongly  dilated  at  tip,  scrobes  meeting 

beneath  the  eyes  ;  mesosternum  protuberant...         COLEOCERUS. 
Rostrum  very  feebly  dilated,  cylindrical  flattened, 
scrobes  not  meeting  beneath  the  eyes  but  turn  - 
ing  forward.     Mesosternum  not  protuberant. 
Elytra  broadly  oval,  scutellum  small.    Metastcr- 

num  short 

Elytra  oblong,  broader  at  base  than  the  thorax, 
scutellum  transverse.  Metasternum  mode- 
rately long 

In  the  last  two  genera  the  articular  cavities  of  the  hind  tibitc  are  shallow, 
the  outer  free  edge  is,  however,  double  in  Eudiagogus.  In  Coleocerus  the 
hind  tibia;  is  truncate  at  tip.  forming  an  oval,  scaly  space,  the  outer  edge 
of  which  is  formed  by  a  moderately  sharp  ridge  not  margii  ed  with 
spinules.  The  tibiae  are  feebly  mucronate  in  all  of  the  genera,  although  the 
contrary  is  stated  by  Lacordaire.

Bathyrh  Lee.  Amer.  Nat.  1874,  p.  4(51. 

Rostrum  not  longer  nor  narrower  than  the  head,  very  short  and  stout, 
alue  prominent  laterally  and  beneath,  tip  emarginate,  in  front  of  each  eye  a 
triangular  impression,  above  a  longitudinal  groove.  Scrobes  sharply  de- 
fined, arcuate  and  confluent  beneath.  Eyes  oval,  pointed  beneath,  not  pro- 
minent. Antennae  moderate;  scape  gradually  clavate,  attaining  the  front 
of  the  eyes;  funicle  7-jointed,  1-3  longer,  the  first  longer  than  the  second, 
3-7  short,  gradually  decreasing;  club  oval.  Thorax  variable,  trapezoidal 
(dispar)  or  transverse  {mavmoratus),  ocular  lobe  broad  and  prominent. 
Scutellum  transvei-se,  enclosed  by  the  elytra.  Elytra  oblong  oval,  parallel,

sliglitly  wider  than  the  thorax  {marmoratus)  or  not.  Mesostcrninn  protuber- 
ant in  tlie  form  of  an  obtuse  spine.  Metasternnm  moderate,  side  pieces  wide. 
Intercoxal  process  broad,  oval  at  tip,  second  segment  longer  tlian  the  two  fol- 
lowing united,  first  suture  strongly  arcuate.  Anterior  and  middle  tibitc  mu- 
cronate,  articular  surface  of  hind  tibia;  internal,  cavernous,  the  tip  truncate, 
and  with  oval  scaly  space.     Claws  free.     Body  oval,  densely  scaly. 

The  scar  left  after  the  disappearance  of  the  deciduous  i)ieee  is  small  and 
difficult  at  first  to  discover,  and  the  genus  was  placed  in  the  following  sub- 
family. (Amer.  Nat.  1874,  p.  461),  Two  other  genera  are  very  closely 
allied  to  this,  and  should  probably  not  be  separated,  rororhipichuH  and 
Periorges.  The  former  has  the  thorax  margined  near  the  base  as  in 
C'oleocerus,  but  the  mesosternum  is  not  protuberant;  the  latter  has  the  pro- 
tuberant mesosternum,  but  not  the  thoracic  margin.  One  of  our  species 
(mcD'inoratus)  might  be  referred  to  Periorge»,  1  ut  the  mesostermun  is  pro- 
tuberant exactly  as  in  Coleocerun,  while  in  tha'.  genus  the  protuberance  is 
slight  and  somewhat  laminiform. 

Two  species  occur  in  our  fauna. 

Thorax  margined  at  the  sides,  at  base dispar. 

Thorax  not  margined marmoratus. 

O.  dispar  Lee.  (Bathyns)  Amer.  Nat.  1874,  p.  462. 

Form  oblong  oval,  densely  scaly.  Head  and  rostrum  as  long  as  the 
thorax.  Rostrum  deeply  sulcatc,  moderately  densely  punctured,  and 
densely  covered  with  rounded  scales,  of  dark  cinereous  color,  a  paler 
line  on  the  vertex.  Thorax  rhomboidal,  gradually  narrower  from  base 
to  apex,  sides  dilated  near  the  hind  angles,  and  with  a  short  sub-acute 
ridge,  disc  moderately  convex,  densely  covered  with  dark  cinereous 
scales,  median  line  and  sides  paler,  a  small  spot  on  each  side  of  middle 
darker.  Scutebum  white.  Elytra  oblong,  not  wider  than  the  exjianded 
thorax,  striate,  stria)  with  moderately  large  punctures,  intervals  flat, 
each  with  a  row  of  short,  erect  hairs;  surface  densely  covered  with 
brownish  scales;  tip,  and  a  short  oblique  band  in  front  of  middle  cinere- 
ous. Body  beneath  and  legs  densely  covered  with  nearly  whi'.e  scales, 
darker  on  the  outer  side  of  the  legs.     Length  .18  inch;  4.5  nun. 

One  specimen.  Arizona,  Dr.  Webb.  From  memory  alone,  I  am  in- 
clined to  think  this  species  identical  with  C.  variegalus  which  I  saw  in  the 
cabinet  of  M.  Aug.  Salle,  of  Paris. 

O.  marmoratus,  n.  sp 

Form  of  dispar,  densely  scaly.  Thorax  broader  than  long,  sides  mode- 
rately arcuate,  widest  at  middle,  disc  moderately  convex,  covered  densely 
with  whitish  scales,  with  black  and  fuscous  sparsely  intermixed,  and  a 
transverse  basal  band  black.  Scutellum  w'lite.  Elytra  oblong  oval,  indis- 
tinctly striate,  and  with  moderately  large  punctures  distantly  placed,  inter- 
vals flat  without  erect  hairs,  surface  densely  scaly;  scales  cinereous  and 
brown  intermixed,  and  with  three  very  irregular  black  fasciic;  the  first  ob- 
lique, the  second  median,  transverse,  the  third  sub-apical.     Body  beneath

and  legs  densely  covered  with  cinereous  and  brown  scales  irregularly  inter- 
mixed.    Length  .16  inch;  4  mm. 

TiiiH  species  is  relatively  more  robust  than  the  preceding.  It  api>ears  to 
constitute  a  form  intermediate  between  tlie  genus  Periorges  and  Coleocerus. 
It  is  certainly  not  the  female  of  dispar  as  suspected  by  Dr.  LeConte. 

Occurs  in  Texas. 

ARACANTHUS  Sch. 

Araeanthxis  Sclionh.  Gen.  Cure,  v,  1,  p.  821. 

Rostrum  scarcely  longer  than  the  head,  stout,  parallel,  finely  canaliculate 
above,  tip  feebly  emarginate.  Scrobes  linear  mo<lerately  arcuate,  passing 
immediately  in  front  of  the  eyes  beneath  the  head,  and  turning  slightly  for- 
ward. Eyes  transversely  oval,  pointed  beneath.  Submentum  with  a  short 
broad  peduncle,  not  emarginate.  Antennaj  moderate,  scape  gradually  cla- 
vate,  attaining  the  middle  of  the  ej'e;  funicle  7-jointed,  1-2  longer,  the  first 
longer  than  the  second,  3-7  gradually  shorter,  slightly  flattened;  club  oval. 
Thorax  slightly  wider  tlian  long,  ocular  lobes  prominent.  Scutellum  very 
small,  triangular.  Elytra  oval,  very  little  broader  than  the  thorax  at  base, 
humeri  rectangular.  Mesosternum  oblique,  metasternum  short.  Intercoxal 
process  oval  at  tip.  Abdomen  normal.  Anterior  and  middle  tibiaj  feebly 
mucronate,  articular  surfaces  of  hind  tibiiB  terminal,  not  cavernous.  Claws 
free. 

This  genus  is  closely  allied  to  Eudiagogun,  and  differs  in  having  the 
thorax  nearly  as  wide  at  base  as  the  elytra;  the  scutellum  very  small,  and 
the  peduncle  of  the  submentum  not  emarginate.  The  genus  was  named,  but 
not  characterized  by  Say. 

A.  pallidus  Say,  Cure.  p.  9;  Compl.  works,  1,  p.  268;  Schonh.  loc.  cit.

Length  .12  inch;  3  mm. 

Many  of  the  scales  covering  the  surface  have  a  slight  cupreous  lustre,  es- 
pecially those  near  the  sides. 

Occurs  in  Texas  and  Missouri.

This  ftiinily  is  by  fnr  tlie  liirj^cHt  in  tlic  Rfijjnrfiophora,  and  tlierctort'  ex- 
hibits a  greater  range  of  viiriiilion  in  some  of  tlic  important  organs  tlian 
can  be  seen  in  tlie  otlier  families.  Certain  of  tlie  most  remarltable  diver 
gences  from  tlie  average  type  may,  however,  be  separated  as  s\ib-familieH, 
cxliibiting  relationsliiiis  with  otlier  families,  without  losing  the  essential 
characters  of  this  family  ;  that  is  to  s.ay,  the  mandibles  without  scar,  the 
tarei  with  the  tliird  joint  more  or  less  dilated,  not  spinous  beneath,  the  an- 
tenna; with  annulated  or  articulated  club. 

Of  such  sub-families  I  recognize  five  in  our  fauna  ;  all  of  very  limited 
extent,  excei)t  the  C urculio iiidw  (f/enuini). 

They  may  be  separated  as  follows  : 

A.  Condyles  of  mandibles  on  outer  side,  motion  lateral. 

^landibles  stout,  feebly  emarginate  at  tip, 
with  the  inner  edge  sharp;  gular  pedun-

tional  cusp:

nent,  peduncle  and  mentum  retracted.  ALOPHID.ffi.  . 
Antenuiu  straight,  gular  margin  not  promi- 
nent; claws  toothed  (p.  130) ITHYCBRID^. 

Mandibles  varying  in  form,  usually  3-toothed, 
sometimes  ol)lique  without  teeth*,  gular 
margin  not  prominent,  peduncle  usually 
long  (p.  131) OUROULIONIDiB. 

B.  Condyles  of  mandibles  on  upper  side,  motion 

vertical  (p.  321) BALANINIDuE. 

Sub-family  I.    SITONID^. 

The  species  of  this  sub-family  have  been  heretofore  classed  with  the 
Otiorhynchide  group  Naupacti.  They  differ,  however,  essentially  by 
family  characters  ;  the  mandibles  are  short,  very  stout,  with  the  outer  side 
convex,  roughly  punctured,  and  quite  destitute  of  the  apical  scar  which 
indicates  the  deciduous  cusp  ;  they  are  broadly  emarginate  al  tip,  and 
the  inner  edge  is  acute.  These  insects  are  easily  known  from  other  Curcu- 
lionida'  by  the  mentum  larger,  more  quadrate,  slightly  concave,  and  sup- 
ported on  a  broad,  but  not  long,  gular  iieduncle.  The  maxilkc  are  exjwsed 
as  in  the  lower  Otiorhynchida;,  and  as  in  all  CurculionidiC.  and  it  tlierefore 
seems  singular  that  Lacordaire  should  have  classed  them  with  his  Adelog- 
nathes  Cyclophthalmes,  without  noting  the  exception  in  this  respect  which 
they  mdkc  in  common  with  Gratopus  and  Elytrodon.\    The  condyle  of 

*  In  De.wioris  tlioy  are  also  toothed  on  tlie  outer  edge  as  In  KhynchitiUee.

feebly  bunded  on  the  elytra.     Length  3.3  mm;  13  inch. 


Sub-Family   II.     ALOPIlIDiE. 

Tlie  small  group  of  Curculionidie,  represented  in  Eurojic  l)y  Alophitu, 
and  in  our  fauna  by  several  other  genera,  is  sufficiently  distinct  in  its  oral 
stru'-ture  to  warrant  its  reception  asa  suli-family.  The  convex  oval  elytra, 
without  humeral  angles,  and  with  tlie  posterior  part  strongly  deflexed, 
added  to  the  more  or  less  rounded  prothorax,  give  an  apjiearance  not  unlike 
ccrt.iin  Otiorhynchidic;  and  the  prolongation  of  the  antennal  grooves  to 
the  tip  of  the  rostrum,  which  is  rather  stout,  increases  the  resemblance. 

There  are,  liowever,  radical  differences  in  the  mandibles;  wliich  are  nearly 
flat  externally  and  punctured;  pincershapcd,  with  a  sharp  e<Ige  at  the  ajiex, 
which  is  more  or  less  emarginatc,  and  without  apical  scar  or  deciduous 
piece.  The  menlum  is  tolerably  large,  trapezoidal  and  ll-'i,  retracted  witli 
the  gular  peduncle,  which  is  broad  ;  the  p(>"terior  edge  of  the  latter  ia 
prominent,  so  that  the  iViOi.th  appeafs  hollow;  the  maxilhe  are  (ixposed,  as 
are  also  the  ligula  and  i>alpi. 

The  beak  is  as  long  as  the  prothorax,  rather  stout,  usually  a  little  wider 
at  till,  with  distinct  apical  wings;  the  tip  is  feeblj'  emarginate.  and  marked 
also  in  the  first  two  genera  with  a  deep  angulated  impression,  from  which

transverse,  narrowed  below,  and  finely  granulated.  The  antenna;  are  gcn- 
iculated  ;  the  scape  long,  the  funicle  seven-jointed  (the  first  and  second 
joints  longer),  the  club  annulated,  oval,  pointed;  the  antennal  grooves 
usually  long,  well-defined,  narrow,  and  reaching  nearly  to  the  lower  angle 
of  the  eye,  except  in  Lophalopliiis,  where  they  are  wider  and  shorter.  The 
prothorax  is  distinctly  lobed  behind  the  eyes;  the  front  coxae  are  contigu- 
ous and  prominent.  The  metiisternum  is  nearly  as  long  as  the  first  and 
second  ventral  segments,  and  the  side  pieces  are  narrow;  first,  second  and 
fifth  ventral  segments  long;  third  and  fourth  united  equal  to  either  of  the 
others.  Legs  motlerute  in  length,  slender;  tibia;  truncate  at  tip,  hind 
pair  not  mucronate  at  the  inner  angle;  tarsi  dilated,  claws  entire,  separate.

Sub  Family  IV.     CURCULIOXID^  (genuini). 

The  species  of  this  sub-family  may  be  recognized  by  the  mandibles  being 
rarely  emarginate  at  tip,  but  either  bi-emarginate,  with  three  apical  cusjis, 
or  obli(iue,  with  three  cusps  on  the  irner  side,  which  sometimes  become 
eflFaced,  or  obsolete.  In  the  first  tribei:  the  inferior  cusp  is  also  smaller,  and 
less  prominent,  but  it  speedily  becomes  more  developed,  and  it  is  b\-  the 
final  dominance  of  that  cusp,  with  the  edge  of  the  mandible  which  corres- 
imnds  to  it,  that  the  oblique  form  with  the  teeth  on  the  inner  edge,  is  as- 
sumed; and  a  still  greater  prominence  of  this  inferior  edge  and  cusp  results

chini  and  Jlarini.  From  them  the  transition  is  easy  to  the  next  subfamily 
Balanlnid.L'  in  wliieh  the  mandibles  are  still  more  depressed,  and  the  eon- 
dyle  instead  of  being  on  the  outer  side  conies  to  the  upper  surface,  so  that 
the  movement  is  vertical,  instead  of  horizontal  as  in  all  other  Coleoptera. 

It  must  also  be  observed  that  in  certain  P/u/tonomini  the  interior  cusp 
becomes  very  small  or  obsolete,  so  that  the  mandibles  seem  to  be  only 
cmarginatc  at  tip.  They  thus  approach  the  two  preceding  sub-families, 
but  are  readily  known  by  not  possessing  tlie  peculiar  characters  whicl»  dis- 
tinguisli  each  of  them.  The  beak  is  not  short  and  flat,  and  the  eyes  arc 
not  round,  as  in  Bitonidie;  the  gular  margin  is  not  prominent  as  in  Alophi- 
dic;  and  the  antenna;  are  not  straight,  nor  the  claws  appendiculate  as  in 
Ithyceridie. 

After  eliminating  tho  tj'pcs  which  seem  of  sufficient  imporUince  to  be  re- 
garded as  hiving  family  or  sub-family  value,  there  still  remains  this  vast 
complex,  whijii  presents  no  difficulty  in  circumscription.  It  nevertheless 
comprehends  so  many  diversified  combinations  and  representations  of  a 
few  simple  cliaracters,  and  under  each  so  many  variations  in  a  f(nv  definite 
directions,  that  much  labor,  and  very  careful  observation  is  ne(!essary  to 
devise  a  sclieme  which  will  enable  the  genera  to  be  naturally  grouped,  and 
easily  recDgnized. 

I  believe  Uiat  the  following  table  will  be  found  sufficient  for  the  proper 
elucidation  of  our  limited  fauna,  and  perhaps  with  a  certain  amount  of  ex-

Tribe  I.  PHYTONO.MiBri. 

Among  the  tribes  in  which  the  ungues  are  simple  and  separate,  and  the 
pygidium  not  exposed,  the  present  one  may  be  distinguished  by  the  form 
of  the  mandibles,  and  by  the  hind  tibiue  being  truncate  at  tip,  with  the  ar- 
ticular surface  terminal,  and  though  somewhat  ol)lique,  not  latenil  as  in 
Hylobiini.  It  follows  from  this  that  the  terminal  spine  representing  the 
spur  is  situated  on  the  inner  side  of  the  apical  surface. 

The  mentum  is  oblong,  and  supported  on  a  gular  peduncle  which  is  not 
longer  than  wide,  and  emarginate.  The  ligula  and  labial  pal|)l  an;  less  de- 
veloped than  in  Hylobiini;  the  maxillte  are  entirely  exposed.  The  mandi- 
bles are  short,  very  stout,  pincer-shaped,  emarginate  at  tip,  (except  in  Phy- 
toHoinm  opimm)  convex  and  sparsely  sculptured  on  the  outer  surface, 
the  basal  condyle  large.  Antennae  inserted  near  the  tip  of  the  beak,  geni- 
culate; scape  long,  club  elongate-oval,  pointed,  annulated,  covered  with 
sensitive  surface;  funiculus  7-jointed;  the  seventh  joint  in  some  species  con- 
nected with  the  club.  Beak  moderately  long,  not  slender,  antcnnal  gro'^'cs 
extending  nearly  to  the  tip,  deep,  dire'"'ed  towards  the  lower  par<  of  the 
eyes,  which  are  more  or  less  transverse  and  narrowed  beneath.  Front  coxaj

One  specimen  from  Pennsylvania  given  me  by  Dr.  Melsheimer,  under 
the  name  adopted  ;  another  from  Canada.  The  mandibles  are  oblique, 
and  not  emarginate  at  tip. 

I  should  refer  this  species  to  Cephnlahjei*,  but  the  eyes  are  not  approxi- 
mate above  as  described  in  that  genus.  It  belongs,  however,  to  the  group 
Bonus  Capiomont,  and  seems  related  to  the  Canarian  P.  irrorntuH  Wollas- 
ton.     I  am  not  at  all  certain  that  it  properly  belongs  to  our  fauna.

One  specimen  from  Greenland,  kindly  sent  me  by  ]\Ir.  Clir.  Drewaen. 
Belongs  to  Capiomont's  sixth  group  Phytonomus. 

3.  P.  setigenis,  n.  sp. 

Moderately  elongate,  black,  densely  clothed  with  yellow-brown  scales, 
and  long  pale  hairs,  which  on  the  elytra  are  arranged  in  rows  ;  protliorax 
strongly  rounded  on  the  sides,  widest  at  the  middle,  with  two  broad  darker 
discoidal  stripes,  and  a  spot  each  side  in  front  ;  elytra  vith  the  alternate 
spaces  tesselated  with  dark-brown,  and  frecpiently  with  a  large  (pindrate 
common  dark  spot  at  the  base  ;  first  joint  of  funiculus  of  antennie  one-half 
longer  than  the  second.     Length  5..')  mm. ;  .32  inch. 

Kansa.s,  two  specimens.  Larger  and  stouter  than  the  next,  and  easily 
known  by  the  hairs  intermixed  with  the  scales,  and  by  the  funiculus  of  the 
antennae  longer  and  more  slender,  with  the  first  joint  conspicuously  longer 
than  the  second. 

This  species  is  allied  to  the  European  P.  Pollux,  but  the  prothorax  is 
wider  in  front  and  more  rounded  on  the  sides,  and  the  setas  of  the  elytra 
are  much  longer  and  more  obvious.

I  know  not  why  Gyllenhal  placed  this  species  among  those  in  which  tiie 
third — seventh  joints  of  tlie  funiculus  are  nodose  ;  they  are  in  reality  as 
slender  and  »Aibturbinate  as  in  any  of  his  first  division.  The  synonym 
seems  to  differ  from  the  typ"  only  by  smaller  size  and  sliglitly  irregular

States,  and  is  by  no  means  rare.  Tlie  form  is  less  elongate  than  in  L. 
appendtculatun,  and  the  prothorax  is  a  little  wider  than  long,  slightly  nar 
rowed  in  front,  and  feebly  rounded  on  the  sides;  the  punctures,  on  remo- 
val of  the  scales,  are  large,  deep  and  densely  placed;  the  scales  are  of  the 
usual  dirt  color,  not  conspicuously  varied  in  coloi-;  though  the  prothorax  is 
indistinctly  trivittate,  and  larger  upon  the  prothorax  than  upon  the  elytra. 
Elytra  about  one-third  wider  than  the  prothorax,  slightly  emarginate  at

San  Francisco,  Cal.  Precisely  similar  in  form  to  the  preceding,  but  the 
beak  is  a  little  stouter  and  very  feel)l}'  carinate  and  sulcate;  tlu>  frontal 
fovea  is  punctiform,  Ijut  not  so  deep;  the  scales  are  of  a  uniform  pale  mud

The  last  ventral  segment  is  impressed  at  the  tip. 

21.  L.  gracilis,  n.  sp. 

Precisely  similar  to  L.  teretirostris  in  form,  size  and  color,  but  the  beak 
is  more  slender,  as  in  imnctirjer,  and  neither  carinate  nor  sulcate;  it  differs 
from  both  by  the  absence  of  the  frontal  fovea.  The  i)rothorax  is  entirely 
uniform  in  color,  and  the  c  .-tra  slightly  mottled  towards  the  tip.  L(!ngtli 
5.3  mm.;  .21  inch.

rounded  at  the  sides,  and  slightly  (;onstricted  in  front;  narrow  lateral 
stripes,  and  a  dorsal  line  of  paler  scales.  Elytra  one-third  wider  than  the 
prothorax,  broadly  emarginate  at  base,  humeri  rounded,  striie  punctured, 
interspaces  wide,  nearly  Hat,  setic  as  in  the  three  preceding  species.  Last 
ventral  segment  impressed  at  the  tii>.     Length  4  mm. ;  .10  inch. 

Nevada,  E.  P.  Austin:  three  specimens,  (^uite  distinct  from  /..  f/rnrilis 
by  the  less  elongate  form  and  more  rounded  sides  of  i)rothorax.  The 
sculpture  of  the  prothorax  is  concealed  by  the  scales  as  usual,  .so  that  I 
cannot  compare  it  as  fully  as  I  desire  with  L.  oregonensis,  which  it  resem- 
bles in  form.  The  latter,  however,  has  the  last  ventral  not  imjiressed  (  ?), 
and  has  probably  the  head  clothed  witli  hair-like  and  not  round  scales.

I  have  one  specimen  of  the  same,  or  a  very  similar  species  from  Texas, 
sent  by  Belfra^e.  Tlie  scales  are,  however,  in  great  part  abnuled,  and 
although  I  perceive  some  differences,  I  am  unwilling  to  indicate  it  as 
distinct. 

MAOROPS  Kirby. 

The  smaller  species  placed  by  Schonherr  in  Listroderes  were  separated 
by  Mr.  Jekel  as  a  distinct  genus,  IlyperodeH  (Ann.  Ent.  Fr.  18()4,  .ICG), 
and  undoubtedly  the  separation  is  a  proper  one.  I  find,  however,  that  the 
two  species  upon  which  Mr.  Kirby  founded  his  genus  Macrops  (Fauna  Bor. 
Am.  199),  belong  to  the  same  set,  and  that  name  must  therefore  have  pre- 
cedence. 

This  genus  is  easily  distinguished  from  the  preceding  by  the  til)ite  being 
stouter  and  less  stronglj"^  mucronate  at  tip,  and  by  the  first  joint  of  the 
funiculus  being  stouter  and  as  long  as  the  second,  except  in  M.  soltitun, 
where  it  is  about  two-thirds  as  long  as  the  second;  the  seventh  joint  of  the 
funiculus  is  wider  than  the  sixth,  but  is  quite  distinct  in  most  of  the  species, 
though  in  others  it  is  rather  closel}-  connected.* 

It  will  be  seen  that  in  the  characters  by  which  this  genus  differs  from 
Listronottis  it  api)roaches  Phytonomun.  Tlie  greatest  differences  will  be 
found,  however,  in  the  proportion  of  the  ventral  segments,  which  in  the 
last  named  genus  are  not  very  unequal,  while  in  Mdcropa  the  third  and 
fourth  arc  very  evidently  shorter,  and  together  are  not  longer  than  each  of 
the  others. 

The  species  are  closely  allied  and  difficult  to  distinguish.  The  descrip- 
tions of  Bohenian  and  Gyllenhal,  though  minute,  are  not  suflicient  to 
enable  me  to  identify  their  species  with  reasonable  certainty,  and  I  there- 
fore content  myself  with  giving  a  list  of  those  named  in  the  books  with 
references,  awaiting  more  abundant  material  and  comparison  with  the 
described  types  for  a  proper  tabulation  of  the  species:

the  seales,  and  the  len^^th  of  the  setie  atrord  good  characters  for  the  recognition 
of  many  of  the  species,  of  which  there  are  probaoly  fifteen  to  seventeen  in  my

EMPIIYASTINI. 


137 


In  this  species,  whicli  is  easily  known  by  the  (leniided  transverse  black 
spot,  sometimes  becoming  a  band,  about  the  middle  of  the  elytra,  the  sec- 
ond joint  of  the  funiculus  is  longer  tlian  the  first,  and  the  tibiiu  are  more 
slender  and  more  bent  at  the  tip  than  in  the  others,  thus  establishing  a  pas- 
sage to  Listronotus. 

Tribe  11.  kmphyastini. 

This  tribe  is  evidently  closely  related  to  Iljilobiini,  and  agrees  with  it  in 
the  structure  of  the  mouth,  but  differs  from  it,  as  from  all  other  tribes  in 
our  fauna,  by  the  peculiar  form  of  the  tibia;,  which  are  fitted  tor  digging. 

The  front  tibitB  are  compressed,  slender,  sub-sinuate,  jjrolonged  beyond 
the  articulation  of  the  tarsus  into  a  broad  jjrocess,  rounded  at  tip,  and  con- 
cave beneath  ;  the  spur  is  small  and  straight ;  the  middle  tibia'  are  roughly 
tuberculate  and  setose,  with  the  apical  margin  repaiul,  dilated  on  the 
outer  side,  and  armed  with  a  straight  fixed  spur  at  the  inner  side:  the  hind 
tibias  are  bent  outwards,  tuberculateandseto.se;  much  thickened  towards  the 
tip,  with  very  large  and  acutely  margined  corbels.  Tarsi  sparsely  setose 
beneath,  and  not  spongy;  third  joint  not  dilated  nor  bilobed  ;  fourth  joint 
moderate  in  size,  claws  slender,  simple  and  divergent. 

The  antenmeare  geniculate  ;  funiculus  7-jointed;  first  joint  longer  ;  2-7 
gradually  broader,  forming  a  perfoliafj  stem  uniting  with  the  club,  which 
is  oval,  annulated  and  pubescent.  Beak  stout,  shorter  than  the  prothorax, 
deeplj'  grooved;  antennal  grooves  extending  to  the  eyes,  which  are  small, 
nearly  round,  and  coarsely  granulated. 

Prosternum  not  emarginate  beneath;  front  coxib  contiguous,  middle  ones 
slightly  sei)arated,  metasternum  short,  side  pieces  narrow,  hind  coxa'  rather 
large,  oval,  widely  separated,  extending  to  the  elytral  margin.  Thighs 
stout,  unarmed.  Ventral  segments  unequal;  tlurd  and  fourth  united  ecjual 
to  the  second  or  fifth;  sutures  straight,  the  first  obliterated  at  the  middle. 

The  above  characters  are  drawn  from  Emphyastes.  The  Australian 
genus  Aphela  only  differs  by  the  legs  being  less  stout ;  the  tibia;  less  ex- 
panded or  thickened  towards  the  tip,  and  by  the  beak  not  being  grooved.

Sea  Coast  of  the  Pacific,  from  Alaska  to  San  Diego;  under  sea-weed  cast 
up  by  the  waves.  The  figure  of  the  antenna  given  by  Lacordaire  is  very 
incorrect. 

This  species  varies  greatly  in  size,  but  I  have  observed  none  intermediate 
between  the  large  and  small  varieties.     Length  4.8-6  mm.;  .lS)-.24  inch. 

Tribe  IIL  iiYliOBliNi. 

The  mandibles  in  this  tribe  have  two  apical  teeth,  of  which  the  lower 
one  is  a  little  shorter  ;  there  is  besides  a  cusp  on  the  inner  edge,  so  that 
they  becomes  three-toothed.     This  normal  form  is  preserved  through  many

of  the  following  tribes,  niocliflo«l  only  by  the  greater  development  of  the 
inferior  I'di^e  unci  eiisp,  which  by  assuming  more  prominence  gives  finally 
an  obli(iiie  form  to  the  mandible.  The  giilur  peduncle  is  longer  than  wide, 
a  little  wider  in  front,  truncate  anteriorly;  the  mentum  is  transverse,  not 
large,  and  the  palpi  are  rather  more  developed  than  in  the  following  tribes. 
The  beak  is  rather  long,  not  slender,  except  in  Pmodes,  and  the  antennal 
grooves  do  not  extend  to  the  tip.  Eyes  transverse.  The  antennte  are 
geniculate  ;  scape  long,  funiculus  7-jointed,  club  oval,  pointed,  annulated, 
entirely  pubescent  and  sensitive,  except  in  Pmodes,  where  the  first  joint 
is  smooth  and  sub-glabrous. 

The  front  coxt:;i  are  contiguous  and  the  cavities  confluent,  except  in 
Pmoden,  where  they  are  slightly  sei)arated.  The  middle  coxie  are  not 
widely  separated;  the  side  pieces  of  metasternum  diagonally  divided,  with 
the  epimera  triangular,  not  attaining  largely  the  base  of  the  prothorax. 
Side  pieces  of  metasternum  narrow,  slightly  dilated  in  front.  Hind  coxae 
widely  separated,  attaining  the  lateral  margin,  or  nearly  so. 

Ventral  segments  unequal,  first,  second  and  fifth  longer;  sutures  straight 
and  deeply  impressed,  except  the  first  which  is  finer  and  sometimes 
slightly  sinuate.     Pygidium  covered  by  elytra. 

Legs  stout,  or  strong  ;  tibiie  armed  Avith  a  strong  hook  at  tip  ;  articular 
face  lateral  ;  terminal  edge  of  hind  tibisu  double,  except  in  Pismdes;  tarsi 
with  third  joint  dilated,  spongy  beneath  ;  claws  simple,  divergent. 

The  species  are  of  moderate  size,  never  very  small,  and  are  sub-cortical 
in  their  habits  ;  they  mostly  infest  coniferous  trees. 

This  tribe  leads  directlj'^  to  the  Erirhinini,  from  which  they  differ  chiefly 
by  the  less  delicately  organized  mouth,  and  generally  stronger  and  coarser 
structure,  and  by  the  double  edge  or  corbel  to  the  terminal  margin  of  the 
hind  tibiiv.  This  character,  common  in  Otiorhynchidre,  now  reappears  for 
the  last  time  in  the  present  family. 

These  corbels  are  very  large  and  wide  in  Pachylobius,  but  narrow  in  the 
other  genera.

HILIPUS  Germ. 

This  genus,  largely  develoiied  in  tropical  America,  is  represented  by  a 
single  rare  species  found  in  Georgia  and  Florida.  E.xcept  that  the  spe- 
cies of  this  genus  are  mottled  with  spots  of  very  small  white  scales,  not 
hairs,  and  that  the  seventh  joint  of  the  funiculus  is  not  connected  wiih  the 
chd),  the  ditlerencos  between  it  and  Ilylobiiis  are  rather  (comparative  than 
absolute. 

The  beak  is  cylindrical,  and  more  curved,  without  anteocular  grooves  ;  the 
antennal  grooves  terminate  at  a  greater  distance  from  the  mouth;  the  eyes, 
postocular  lobes  and  emargination  of  the  i)rosternum  are  similar.  The 
thighs  are  efpially  clavate,  and  sinuate  beneath,  but  the  tooth  is  much 
larger  and  broader ;  the  tibiiu  are  compressed,  bent  inwards,  equally 
strongly  armed  with  a  terminal  hook,  but  much  less  sinuate  on  the  inner 
side.  The  lirst  ventral  suture  is  deeper,  and  more  strongly  angulated  at 
the  middle.  The  sculpture  is  much  coarser  and  sparser,  and  the  spaces  be- 
tween the  large  punctures  are  smooth  and  polished.

than  inner  part  of  the  apex  of  the  til)iic;  corbels  wanting. 

I  am  not  satisfied  with  the  position  of  this  genus,  and  am  disposed  to 
believe  that  it  should  be  placed  as  a  sejiarate  tribe.  Thomson  (Skand.  Col. 
vii,  218)  associates  it  with  Traehode^,  but  there  does  not  appear  to  iiie  any 
resemblance  between  the  two.  The  definition  of  his  tribe  Pi»sodin<i  does 
not  at  all  apply  to  Trachodet,  in  which  the  nietastenium  is  very  short,  and 
the  club  of  the  aiitennie  entirely  pubescent  and  sensitive. 

These  insects  live  under  bark  of  pine  trees,  and  are  sometimes  very  inju- 
rious.   Then;  are  evidently  several  species  in  our  fauna,  but  the  ditVerences 
are  not  very  obvious,  and  it  is  quite  possible  that  a  careful  comparison  with 
foreign  speiiies  might  reduce  the  number  now  recognized  as  distinct. 
Prothorax  broader  than  long,  more  suddenly  narrowed

from  the  two  following  ypecics  by  the  hind  angles  being  rectangular.  The

This  species  (luite  resembles  in  size  and  form  P.  d'lbiun,  except  that  the 
sides  of  the  prothorax  are  more  rounded  behind,  so  that  the  basal  angles 
become  still  more  obtuse  and  rounded.  The  prothorax  is  more  densely

i  ■'    ' 


The  diaracter  which  distinguishes  this  from  all  neighboring  tribes,  is 
that  the  elytra  are  less  extended  on  the  flanks  of  the  nietathorax  and  abdo- 
men, so  that  the  lateral  angles  of  the  first  ventral  segment  become  visible. 

The  body  is  never  very  stout,  and  freciuently  is  almost  linear.  The 
gular  peduncle  is  soiuetlmes  short,  sometimes  long,  enmrginate  at  tip ; 
mentum  large,  flat ;  ligula  feebly  or  not  prominent ;  palpi  much  less  de- 
veloped than  in  llylohiini.  Tibia;  more  or  less  macronate  at  tip;  articular 
surface  lateral;  ccn'bels  wanting;  claws  connate  at  base,  or  at  least  approxi- 
mate. Antenna;  sometimes  feebly  geniculate  ;  joints  of  funicle  gradually 
broatlcr  ;  club  elongate  oval,  annulated,  pubescent  and  sensitive. 

Tlie  otlier  characters  are  variable.  Tlie  beak  is  either  short  and  thick, 
or  long  and  cylindrical;  the  tarsi  are  dilated  and  spongy  beneatli,  with  the 
third  joint  broad  und  bilobed,  or  only  hairj',  with  the  third  joint  shorter 
and  emarginnte.  The  first  and  second  ventral  segments  are  long  and  con- 
nate ;  in  the  elongate  species  the  other  segments  are  moderately  long  ;  in 
the  species  wi'h  tiiick  short  beak  they  are  shorter.  The  antenna;  are  in- 
serted at  a  variable  distance  from  the  tip  of  the  beak. 

Sexual  differences  are  not  apparent  in  the  short  beaked  species  ;  in  some 
of  the  elongate  forms  the  beak  is  longer  in  the  female. 

Giiulational  characters  are  observed  in  the  form  of  the  beak,  antennte, 
tarsi  and  daws,  varying  by  almost  insensilde  degrees,  so  as  to  render  ihe 
classiticalion  of  this  tril)e  very  difHcult.  After  several  eflbrts,  I  am  onl}' 
able  to  offer  the  following  table  for  the  jdentification  of  the  genera  I  have 
examined: 

Beak  flat,  stout,  more  or  less  grooved,  somewhat  dilated  at 
tip  ;  prothorax  angulated  on  the  sides  near  the  tip,  then 
suddenly  constricted.  Antennic  rather  stout,  feebly 
gcnioiilated  ;  ventral  segments  !l-5  shorter  than  in  the 
sulisecpient  genera.  Tarsi  usually  not  spongy  beneath, 
in  whicli  ease  the  third  joint  is  emarginate,  not  bilobed...  2. 

IJeaU  cylindrical,  rather  stout,  not  dilated  at  tip  ;  pn^thorax 
usually  not  angulated  at  the  side  ;  ventral  segments  ;5-5 
not  so  short;  tarsi  usually  s|)ongy  beneath,  claws  connate 
at  h\\9*i 4« 

lieak  cylindrical,  varying  in  length,  generally  smoother 
tlian  ill  the  i)receding  genera;  anfennie  less  approximate 
to  tiio  tip;  i>rothorax  not  angulated  at  the  sides:  ventral 
segment  !)-5  not  very  short ;  tarsi  spongy  ))eneath,  third 
joint  broad,  bilobed  ;  claws  connate  at  base;  second  joint 
of  funielc  equal  to  first TjIXUS.

OLEONOPSIS  n.  g. 

I  hare  been  obliged  to  sei)arate  as  a  distinct  genus,  one  species  found  in 
Texas  and  Colorado,  which  diflers  from  C7t'««i«.tby  stouter  and  fiatter  beak,, 
the  form  and  method  of  coloration,  and  by  the  joints  of  the  funiculus  of 
the  antenna\  2-0  being  nuire  clo.scily  united.  It  <liflers  from  StephnnMle- 
onuH  l)y  tiie  hind  tarsi  broader,  the  third  joint  not  shorter,  deeply  bllobed, 
with  the  lobes  spongy  beiu'ath.  I  cannot  identify  it  with  any  of  the 
numerous  genera  nu-ntioned  l)y  Mr.  Chevrolat,  though  it  would  quite 
I)08sibly  enter  into  one  of  tiiem.

OLEONUS  Sell. 

Allliougli  the  following  si)eeies  diJIer  in  minor  details  of  structure,  which 
liy  some  entomologists  are  regarded  as  of  generic  value,  there  is  such  a 
general  resemblance  in  appearance  and  in  the  more  important  characters, 
that  it  seems  more  natural  to  regard  them  as  constituting  one  genus.  I  am 
the  more  conlirmed  in  this  belief  from  the  impossibility  of  placing  them 
with  any  satisfaction  in  the  groups  established  on  the  species  of  the  other 
continent,  then\selves  very  indefinite  in  extent. 

I  would  therctbre  include  under  this  head  all  the  species  in  our  fauna  in 
which  the  beak  is  stouter  than  in  Lix%i»,  but  not  dilated  at  tip  ;  the  gular 
peduncle  is  not  so  broad  and  short  !!s  in  the  preceding  genera,  but  is  shorter 
than  in  Lirm;  there  is  a  dillercnee  )etween  the  species  in  this  character, 
it  being  longer  in  proportion  to  tiio  increasing  slenderness  of  the  beak. 
The  front  and  middle  tarsi  are  broad,  ,'he  third  joint  at  least  spongy  and 
bilobed  ;  the  hind  tarsi  are  liaiiy  beneath  in  the  first  division,  but  broad 
and  spongy  in  the  second.  The  gi'neral  tendency  of  the  pubescence  is  to 
form  longitudinal  stripes,  and  not  transverse  or  oblique  bands.  The  body 
is  elongated,  resembling  Li.vii». 

Our  species  may  be  thus  tabulated  :

The  species  of  this  genus  arc  generally  more  slender  than  those  of 
Cleonus,  though  not  always.  The  tarsi  are  broad  and  spongy  beneath, 
with  the  third  joint  deeply  bilobed.  The  beak  is  cylindrical,  not  thickened 
at  tij),  usually  slender,  excei>t  in  L.  pleurdlh  and  te.rtinmt,  and  not  cari- 
nated,  except  in  L.  pleuralii  and  sylrius-  The  antennal  grooves  commence 
at  some  distance  from  the  tip  of  the  beak.  The  antenna*,  except  in  A.  pleii- 
raliit  and  texanus  are  slender,  with  the  first  joint  of  the  funiculm  thicker, 
and  the  second  as  long  as  the  two  following  united  ;  in  those  two  the  funi- 
culus is  less  elongated,  less  slender,  and  the  second  joint  is  somewhat  less 
elongated. 

The  species  are  numerous  and  difticult  to  distinguish;  they  are  covered 
with  a  jioUinose  yellowish  powder  which  is  easily'  rubbed  olT,  and  in  addi- 
tion, some  of  them  are  pubescent.  In  several  species  the  apices  of  the

the  position  wliicli  it  has  in  tlie  next  group.  The  antennal  grooves 
are  directed  against  the  eyes,  and  do  not  converge  lieneatli.  The  s(aipe 
nearly  or  (piite  attains  tlie  eyes,  and  tlie  first,  and  usually  tlie  second

gi.i,  which  may  possibly  lielong  to  this  sp(;cies,  if  not,  it  will  indicate  a 
new  one  closely  allied.  In  well  preserved  spee-imens  liie  pulie.sc<-nce  is 
very  coarse  and  mottled  in  color.  The  posterior  callus  of  the  elytra  is

Jieim's  expression,  "eli/lriH  ante  npireni  atrinque  tuhercido  inxtni.ctiK." 

Two  smaller  specimens  from  Alaska  have  the  thorax  less  rounded  on  the 
sides  near  the  tip,  and  in  one  of  them  there  is  a  distinct  smooth,  narrow, 
dorsal  vitta;  they  were  sent  to  nu'  as  h'rir/n'nn.K  rextitiin  Mann.,  a  very  dif- 
ferent species,  which  has  the  lieak  pimclureil  but  not  striate. 

Four  specimen.s  of  small  size  were  collected  by  Mr.  Crotch  in  the 
M(*jave  Desert,  Cal.,  which  I  would  teini)orarily  refer  to  this  sju'cies. 
They  are  yellow  brown  with  a  broad  darki'r  stripe  on  each  elytron  They 
agree  in  form  with  the  Eastern  specimen,  and  are  a  little  more  robust  than 
those  from  Alaska.     Length  2.5  mm;  .10  inch. 

A  larger  series  of  well-i)reserved  .specimens  will  perhaps  show  the  pro- 
priety of  receiving  these  three  forms  as  distinct  species.

Group  II.   Demnorhlne*. 

In  the  genera  constituting  this  grou))  the  beak  is  slender,  and  separated 
from  the  head  by  a  sharply  defined  transverse  line,  or  constriction.  In  our 
genera  the  claws  are  connate  at  base,  but  as  this  character  is  not  mentioned 
in  the  Kuropean  genus  Sharpiii  (Tournier,  Ann.  Ent.  Belg.  xvii,;  and  is 
somewhat  variable  in  Smicron^.i;,  I  do  not  know  that  it  is  properly  of 
groui)  value.  The  mandibles  are  truncate  at  tip,  and  toothed  both  on  the 
inniir  and  outer  edge  as  in  Ilhynchitidie.  The  prosternum  is  emarginate 
in  front,  and  the  ventral  sutures  are  very  slightly  curved  at  the  sides.  The 
antennal  grooves  descend  obliquely  and  are  almost  confluent  behind.

DESMORIS  n.  g. 

This  genus  corresponds  closely  with  Krirhinun,  except  in  the  ditlVrences 
Indicated  in  the  definiticm  of  the  group,  viz.,  the  connate  claws,  the 
obliipie  antennal  grooves  which  ate  nearly  confiuent  behind,  and  the  beak 
constricted  at  base.  The  second  joint  of  the  funicle  is  as  long  as  the 
first,  but  more  slender.  The  thighs  are  clavate,  unarmed.  The  tibia' 
slightly  mucronate  and  trunc^ate  at  tip,  nearly  as  lon.^  as  the  thighs  ;  tarsi 
dilated,  third  joint  deeply  bilobed,  fourth  joint  long;  claws  small,  ((mnate 
nearly  to  the  tip. 

The  api)earance  is  that  of  Balaninus  in  miniature,  the  eyes  arc  rather 
large  and  transverse,  the  sides  of  the  prothorax  .scarcely  lobed,  and  the

SMIORONYX  Sch. 

This  genus  contains  small  species  which  only  differ  from  I'urhi/tt/rhiuH 
by  the  second  joint  of  the  funiclo  being  shorter  than  the  lirst,  and 
frequently  not  longer  than  the  third  ;  the  scape  reaches  to  tl'.e  eyes.  The 
postocular  lobes  of  the  protlnu'ax  ant  sometimes  distinct,  and  tlie  prosler- 
num  is  moderately  einarginate  in  front.  The  beak  is  shorter  than  in 
DeHiiiorin,  and  is  slightly  thicker  at  base  ;  the  transverse  constriction  is 
well  defined,  and  the  pubescenc(;  at   the   i)ase  of  the  beak   rises   into  two 

tuns. 

The  form  varies  somewhat,  the  first  species  rese?nbles  Piirfii/lf/rhiuK  by 
the  strongly  rounded  sides  of  protiiorax  and  ovate  tdytra  ;  otiiers  resemble 
in  miniature  Bori/loinan,  but  the  thighs  are  noltoothe<l,  and  the  claws  are 
small  and  connate  almost  to  the  tips.  Others  again  have  tint  claws  approxi- 
mate, but  s(;arcel3'  connate. 

The  genus,  even  as  thus  defined,  s(!ems  to  me  somewhat  heterogeneous, 
and  with  more  careful  study  will  be  found  jierhaps,  to  contain  (dements 
representing  other  Kuropean  genera.  Il  ^\•\\]  iu;  for  future  investigators  to 
determine  if  our  species  shall  be  partitioned,  or  the  European  forms  con- 
densed. 

The  species  are  difficult  to  define,  and  the  table  given  is  not  very  satis- 
factory. 

Second  joint  of  funide  of  antennic  not  longer  than  third  ;  claws

Kansas ;  one  specimen .  A  very  small  species,  related  to  S.  (yrJdouhs, 
and  easily  known  by  tli(!  narrow  scales  and  rounded  sides  of  the  protliorax. 
The  scales  are  partly  abraded,  but  ajjpear  to  be  mottled  in  color. 

Group  III.     Eiiisnoiiil. 

Following  the  example  of  Lncordnire,  I  recognize  as  a  distinct  group  f 
small  number  of  genera  -which  are  closely  related  to  the  Krirhini  proper, 
and  like  tlu'm  have  the  antennal  grooves  directed  against  the  eyes  ;  they 
diffcir  in  having  the  eyes  larger  and  more  prominent,  and  separated  from 
the  margin  of  the  protliorax  by  the  head  being  more  or  less  prolonged  be- 
hind. Tile  head  thus  recalls  the  form  already  seen  in  Rhinomacer  and 
lihynchiteK,  though  otherwise  there  is  no  resemblance. 

The  two  sj)e(,'ies  in  my  collectioi.  resemble  in  appearance  small  Dorytomus 
but  the  thighs  are  unarmed,  and  the  second  joint  of  the  funicle  of  the 
antennie  is  sliort. 

I  will  for  the  present  refer  them  to  the  genus  Phyllotrox,  though  they 
ditl'cr  from  the  description  given  by  Lacordaire  (Gen.  Col.  vi,  .jOo),  by  the 
first  veniral  suture  being  well-marked. 

PHYLLOTROX  Scli. 

1.  P.  nubifer,  n.  sp. 

Elongate,  fuscous,  thinlj-  clothed  with  golden  pubescence  ;  antenna?,  legs 
and  elytra  fulvous,  the  latter  with  the  suture  and  scutellar  region  more  or 
less  blackish.     Length  1.8-2.8  nun.;  .OT.'i-.Oi)  inch.

channeled  from  between  the  antenna'  for  a  short  distance;  eyes  rather  large, 
liromineiit ;  antennaj  yellow,  with  the  scape  reaching  to  the  eyes.  First 
joint  of  funicle  stout,  and  inoderately  long,  followed  bj-  six  short  joints, 
club  oval,  pubescent.  Protliorax  not  lolied  behind  the  eyes,  longer  than 
wide,  narrowed  in  front,  feebh  rounded  on  the  sides,  slightly  constricted 
near  the  tip,  rather  densely  i)unctured,  thinly  clothed  with  shining  jellow 
hair.  Elytra  wider  than  the  i>rotliorax,  elongate,  humeri  rounded,  strite 
with  dose-set  punctures,  intersiiaces  densely  ininctulate,  and  sparsely 
pubescent,  brownish-yellow,  with  the  scutellar  region  and  fre(;uently  the 
suture  d  'rk.  Body  beneath  dark,  strongly  punctured  ;  abdomen  and  legs 
brownish-yellow.  Thighs  not  toothed,  rather  thick  ;  tibia;  stout,  truncate 
and  not  armed  at  tip,  tarsi  rather  broad,  third  joint  wider,  deeply  bilobed; 
claws  simple,  divergent. 

This  insect  strongly  resembles  the  figure  of  Brachonyx  indiyena  Herbst, 
as  given  by  Duval,  Gen.  Col.  Eur,  iv,  pi.  19. 

I  have  seen  a  varietj'  from  Colorado  in  the  collection  of  !Mr,  Ulke,  in

his  work,  and  the  name  changed  to  JVotiodes.  Meanwhile,  however,  En- 
dnlus  had  been  proposed  by  Laporte,  in  a  systematic  work,  and  being  ac- 
companied by  proper  description  must  of  course  take  precedence.  The 
species  occur  on  grasses  near  wafer  ;  of  those  described  thus  far,  only  one  . 
properly  belongs  to  the  genus,  the  others  will  be  found  under  Oni/rhi/lis

The  species  which  constitute  this  genus  arc  very  similar  to  certain 
Jiagom  in  form,  size  and  sculpture,  but  dill'er  by  having  the  la.st  tarsal 
joint  comparaliv(dy  smaller,  and  the  claws  slender  and  smaller.  They 
also  dill'er  by  having  the  articular  surface,  of  the  hind  tibiae  ai)ical, 
und  not  lateral  ;  the  edge  of  the  articular  surface  is  fringed  with  small 
s|>inesasin  many  Erirhuu,  and  the  si)ine  at  the  inner  side  is  long  and 
slender,  resembling  at  tirst  sight  the  t(U'minal  hook  of  liiujouit.  The  fu- 
Diculus  is  ((-jointed;  first  joint  longer  and  stouter,  second  a  little  longer  than

Group  V.  Stcnoiiclmi. 

This  genus  is  included  by  Laoonlaire  in  bis  group  Storeide.i,  but  it  seems 
to  me  that  the  remarkable  combination  of  characters  re(iuires  that  it  should 
be  received  as  a  separate  group,  with  the  following  definition: 

Body  clothed  with  a  dense  crust  of  scales;  beak  short  and  broad,  not 
longer  than  the  head;  antennal  grooves  very  short.  Antcnufe  insei'ted  on

Southern  and  Western  States,  to  California,  where  it  was  found  alnind- 
iinlly  l)y  .Mr.  t'rotel,  and  myself  at  San  Diego.  The  reason  given  by 
Schunherr  for  changing  the  name  under  which  he  first  delined  this  genus  is 
uot  a  valid  one.  Even  if  there  wi'fe  in  Dejean's  Cataloirue  a  genus  Stciiop- 
eliuti.i  (which  is  not  the  case  in  the  latest  edition),  it  could  have  no  prece- 
dence over  the  name  as  substantiated  by  description.  Tlie  use  of  Monius  to 
indicate  this  genus  is  therefore  incorrect. 

Group  VI.     Ilrnrhypl. 

The  genus  BnicJn/pus  is  placed  by  Lacortlaire  in  hi.'^  group  }'JrirIii'>iiiIe.t  ; 
it  ditlcrs  from  llie  other  genera  of  that  ilivision  by  the  narrow  linear  form. 
Though  the  three  species  described  below,  do  not  exactly  agree  with  the 
generic  description  given  by  Schonherr  and  Lacordaire,  I  think  tluit  they 
accord  sullicienlly  to  indicate  th<'  propriety  of  associating  them  together  as 
a  special  group. 

As  hero  estaiilished,  the  J]r(ifJti/pi  i\ix'  nearly  related  to  ITiidronomi,  but 
ditVer  by  tin;  third  joint  of  tlu^  tarsi  being  more  or  less  bilobcd,  and  the  hind 
tiliiie  triuicate  at  tip,  not  unguiculate,  but  only  feebly  nuicronate,  with 
the  articular  surface  terminal.  The  tarsi  are  either  broad  or  narrow,  the 
third  joint  sometimes  but  little  dilated,  and  the  last  joint  long,  with  large 
divcrgci,  '  iws.  The  body  is  narrow,  covered  with  a  dense  water-proof  crust 
of  scales,  as  in  G rypto pi  I  i\m\  Hydronomi.  The  beak  is  straight,  cylindri- 
cal, moderately  stout,  and  as  long  as  tlu:  prothorax  ;  the  antennal  grooves 
run  directly  to  the  eyes  and  converge  but  slightly  behind;  they  commence 
at  a  varying  distance  from  the  mouth.  The  autennfc  are  slender  ;  funi<le 
7-joiiited,  first  and  second  joints  elongated  in  our  genera,  :'-T  gradually 
broader,  club  oblong-oval,  annulated,  entirely  covered  with  sensitive  sur-

beneath,  not  excavated.  T^egs  long,  slender,  thighs  moderately  clavate,

LIXELLUS    n.  g. 

A  small  species  of  still  narrower  form  constitutes  this  genus.  It  has  pre- 
cisely the  appcMiance  in  miniature  of  a  slender  LixuK,  and  dilVers  from 
Aiicliodonun  by  the  third  joint  of  tlie  tarsi  licing  not  wider  than  the  second, 
and  not  bilobcd  ;  the  fourth  tarsal  joint  is  as  long  as  the  others  united,  and 
the  claws  are  large  and  divergmit.  The  thighs  are  less  clavate,  the  tibioc 
strongly  bent,  and  the  front  and  middle  pairs  are  serrate  on  the  inner  edge 
from  the  middle  to  the  tip  ;  they  are  all  feebly  mucronate  at  tip.  The  beak 
is  shorter  than  the  protliorax,  rather  stout,  nearly  straight,  and  the  anten- 
nal  grooves  commence  near  the  tip  ;  the  funiculus  is  (i-joiiited,  with  the 
tirst  and  second  joints  longer,  the  joints  3-0  short,  slightly  wider,  club 
elongate  o'mI,  acute,  annulated,  pubescent. 

L.  fUiformis,  n.  sp. 

Very  eloilgate,  cylindrical,  black,  covered  with  extremely  small  brown 
scales,  motth'd  in  color.  IJeak  oi)a(pie,  punctulate,  and  scaly.  Protliorax 
longcu-  than  wide,  feebly  constricted  in  front,  sides  nearly  straight,  AX'iy 
densel.v  punctulate.  Elytra  little  wider  than  the  protliorax,  stri;e  punc-

brown,     Length  4.!!  mm, ;  .17  inch. 

One  specimen  from  Canada,  and  one  from  Oregon. 

Group  VIL     HydronoMil. 

The  same  varnish-like  covering  noticed  in  the  three  preceding  groups  is 
retained  in  this,  the  species  of  which  are  also  found  on  plants  near  water. 
They  arc  easily  distinguished  by  the  longi'r  and  more  slender  legs,  the;  tibitc 
curved,  and  frcquentl}' serrate  on  tlie  inner  side  and  strongly  hooked  at  tip. 
Tlie  tarsi  are  usually  slender,  the  third  joint  frequently  not  dilated,  and 
the  last  joint  moderate  or  very  long,  with  stout,  simple,  divergent  claws. 
Tlic  prosternum  is  usually  broadly  sulcatc.

Our  genera  may  be  tabulated  as  follows  : 

Club  of  aiiteiuuc  entirely  sensitive 2. 

"  "     partly  sniootli  and  shining  ;  pros- 

ternnni  not  exeavated LISSORHOPTRUS. 

3.  Proihonix  feebly  constricted  in  front BAGOUS. 

"  very  strongly  constricted  in  front. ...  PNIGODES. 

LISSORHOPTRUS  n.  g. 

This  is  the  genus  indicated  without  characters,  and  not  named  by  Laror- 
daire.*  It  is  founded  upon  Biifjoiix  Kunplcx  Say.  It  dillers  remarkably 
from  the  other  genera  of  the  group  by  the  antennsr,  the  club  of  which  is 
smooth  and  shining  for  two-thirds  the  length,  and  aiinuiatedonly  near  the 
tip  ;  the  funiculus  lias  but  six  joints,  of  which  the  tlrst  is  stout,  and  the 
second  a  little  longer  than  the  otliers,  which  increase  slightly  in  thickness. 
The  jirosternum  is  flattened,  not  excavated,  transversely  impressed  in  front 
of  the  coxic,  wliich  arc  very  large;  ;  tibia!  not  very  slender,  somewhat 
curved,  armed  with  a  terminal  book.  Tarsi  narrow,  last  joint  as  long  as 
the  two  preccnling,  claws  slender,  approxiniate.  Beak  stout,  as  long  as  the 
prothorax.     Antennal  grooves  suddenly  dellexed. 

This  is  again  a  genus  of  transition,  and  onl}'  dillers  from  0 n i/ch ylia  by 
the  third  joint  of  tarsi  not  emargin!it(>,  by  the  peculiar  antennal  club,  by 
the  tibia'  armed  witli  stronger  terminal  hook,  and  the  articular  surface 
even  of  the  hind  pair  lateral.

Aliddle  and  Southern  Slates  to  Texas.  Say's  description  is  far  from 
sufficient. 

3.  L.  apiculatus.  Ifofiodes  apioihifus  Cwy]\.,  Sch.  Cure,  iii,  !130. 

Southern  States  and  Texas.  Only  differs  from  the  prcci-ding  by  the 
usually  larger  si/e,  and  by  the  transverse  impression  at  the  middle  of  the 
sides  of  the  prothorax  being  wanting. 

BAGOUS  Germ. 

The  essential  characters  of  this  genus  consist,  in  my  opiniini,  in  the  tibiti,' 
l)eing  slender,  strongly  curved  and  armed  at  the  tip  with  a  strong  hook,  so 
that  the  articular  surfaces  !)(■■  ome  lateral;  the  tarsi  are  narrow,  not  spongy 
beneath,  though  the  third  joint  is  sometimes  wider  and  emarginate.  The 
claws  are  divergent,  sometimes  rather  large.  The  club  of  the  antenuiB  is 
entirely  pubescent,  sensitive,  and  larger  than  usual  ;  the  antennal  grooves 
are  deej)  and  extend  to  the  cy<;s  ;  the  beak  varitjs  in  form.  The  prosicr- 
num  is  broadly  and  dee[tly  excavated  in  front  of  the  coxte,  and  the  groove 
is  sharply  limited  at  the  sides  by  ridges  ;  the  postoeular  lobes  arc;  large.

One  specimen,  Kansas  ;  and  one  from  Florida. 

13.  B.  transversus,  n.  sp. 

Robust,  less  convex,  bliu'k,  covered  with  blackish-graj'  scales.  Beak 
stout,  curved,  as  long  as  the  prothorax,  naked,  punctulate,  sub-carinate 
nciir  the  base,  lateral  grooves  deep;  frontal  fovea  large.  Prothorax  nearly 
one-half  wider  than  long,  sides  sinuate,  very  strongly  constricted  in  front, 
verj''  finely  granulate.  Elytra  uneven,  marked  with  vague  impressions,  one- 
half  wider  than  the  prothorax,  hum(!ri  prominent,  slightly  rounded,  posterior 
callus  large,  obtuse  ;  strise  fine,  interspaces  feebly  convex.  AntenuiO  and 
legs  nearly  black,  tarsi  moderately  long.     Length 2.3  mm.;  .15  inch. 

Detroit,  one  specimen;  Hubbard  and  Schwarz.  Remarkable  for  the  form 
of  the  prothorax,  by  which  an  excellent  transition  to  the  next  genus 
Pnigodes  is  established. 

PNIGODES  n.  g. 

This  new  genus  is  closely  related  to  Bar/om,  and  has  the  prosternum 
similarly  excavated.  There  is  also  no  ditl'erence  in  the  beak,  which  is  stout 
and  curved,  nor  in  tlu;  antennie,  which  have  the  funicle  7-jointed;  Ibo 
first  joint  is  stouter  and  the  second  longer  than  the  others,  which  increase 
gradually  in  thickness,  and  the  cluli  is  pubescent  and  annulaled.  The  legs 
are  stouter  than  in  B<ig<)u,n,  the  tibiae  sinuate  on  the  inner  sid(s  hooked  at 
tip ;  tlu!  tarsi  rather  short,  joints  1-3  eipial,  fourth  nearly  as  long  as  the 
others  united,  (Haws  divergent. 

The  form  of  body  is,  however,  remarkable.  The  prothorax  is  wider 
than  long,  narrowed  behind,  widely  lobcd  on  the  sides  before  the  middle, 
then  suddenly  and  very  strongly  constricted  and  tubulate.  The  elytra  are 
■wider  Uian  the  prothorax,  with  the  alternate  interspaces  elevaicd,  and  a 
callus  at  the  hind  extremitj'  of  the  fifth;  the  humeri  are  very  prominent 
and  rounded,  not  angulated.

Tliis  proup  is  establisherl  upon  one  small  species  of  pale  brown  color, 
which  lives  und<'r  sea-Aveed  cast  up  by  the  waves  at  San  Die^o,  Calitbrnia. 
It  ditlcrs  irreatly  from  all  the  otlier  members  of  the  trilie,  by  the  front 
coxie  wliich  are  not  absolutely  contij^uous,  but  separated  by  a  very  narrow 
lamina  of  prosternuin,  and  by  the  veiy  short  metasternum,  only  one-third 
the  length  of  the  first  ventral  segment. 

In  color,  form  and  sculpture  it  resembles  EinpJu/aitteit,  but  dill'ers  from 
that  genus  by  such  strong  structural  characters,  that  I  cannot  venture  to 
place  them  together  in  one  tribe. 

Body  clothed  witii  very  sparse  pubescence.  Beak  cylindrical,  slightly 
curved,  as  long  as  the  jii-jthorax,  not  very  slender;  mandibles  of  normal 
form;  antennal  grooves  commencing  near  Hk;  tip,  extending  to  the  eyes, 
which  are  small,  rounded,  and  coarsely  granulated;  front  continuous  with

unnatural  grouping  of  genera  agreeing  only  in  convex  body,  short  meta- 
sternuni,  and  absence  of  wings.  The  beak  is  rather  slender,  as  long  as  the

In  all  Iho  preceding  trihcs  the  tarsal  claws  are  simple,  usually  separate 
and  divergent,  rarely  connate  ;  in  this,  as  in  several  of  lliose  wh.cli  follow, 
they  are  toothed  ;  tiic  tootli,  however,  is  broad  and  not  very  i)roniinent, 
giving  the  form  termed  ai>pendiculate.  The  species  are  easily  known  from 
those  of  other  tribes  by  the  protlKU'ax  being  narrowed  at  base,  an<l  somc- 
wliat  pedunculate.  Several  of  them  arc  shining  black  and  glabrous,  so 
that  thoy  resemble  in  appearance  ants.

a  gfMieral  resemblance  to  an  ai)ten)us  Ci/nips. 

The  other  characters  of  the  tribe  and  genus  are  as  follows  ;  Beak 
rather  stout,  straight,  nearly  as  long  as  the  prothorax,  subcylindrical, 
not  emarginate  at  tip;  antennal  grooves  extending  in  front  of  the  inser- 
tion of  the  antenna',  converging  behind,  directed  below  the  eyes,  which  are 
distant  from  the  prothorax,  rounded,  and  tinely  granulated;  matidibles  of 
normal  form,  mentum  and  labial  palpi  small,  gular  peduncle  narrow, 
long;  antenn;e  inserted  about  one-third  from  the  tipof  the  l)eak,  scape  long, 
slender,  extending  to  tlu;  back  part  of  the  eyes;  funicle  7, jointed;  first  Joint 
stouter  but  only  slightly  hmger  than  the  second;  2-7  gradually  a  little

thorax without  postocular  lobes;  i)rosternum  broad,  short,  not  i.-marginate.

The  larva  lives  upon  the  kernel  of  the  plum,  like  Cunotrachelmt  nen- 
uphar. Mr.  liilcv  inl'orms  nu;  that  he  has  n^ason  to  believe  that  ihe  eijfiis 
not  pushed  by  tlie  lieak  of  the  female  deep  into  tlu;  fruit,  as  is  tlie  case 
with  that  species,  but  i.s  laid  on  the  surface,  whence  the  larva,  when  tirst 
hatched  burrows  to  the  seeds. 

Mr.  Walsh  veiy  pni|)erly  suspected  that  this  inseci  should  he  separated 
as  a  distinct  ge'ius.  1  rejirel  to  iiave  led  him  into  error  by  not  recogiuzing 
the  species  as  ideiitieiil  witli  my  previously  descril)cd  A.  neiitdlariH,  which 
waa  founded  upun  a  much  smaller  specimen  from  a  far  distant  locality. 


ANTHONOMUS  Germ. 

The  species  of  Ihis  genus  are  quite  numerous,  and  although  agreeing  in 
the  more  important  character.*,  diller  in  such  nuvnner  as  to  indicate  the  pro- 
priety of  future  subdivision.  For  the  purpose  of  making  these  subdivis- 
ions natural,  a  profound  study  of  the  exotic  species  will  be  necessary.  I 
can  at  present  merely  mention  .some  of  the  variant  structures  which  I  have 
observed. 

The  presternum  varies  in  length,  being  shortest  in  A.  elegans,  and  long- 
(ist  in  A.  rufipcH  and  clonrKituK.  The  fifth  ventral  segment  is  not  longer 
than  the  fourth  in  most  species,  but  in  A.  elomjatuK  and  some  others  of 
Division  B  it  is  quite  distinctly  longer  and  flatter,  as  in  Erirhinini,  and 
in  these  species  the  jn'gidium  is  not  exposed.  Tlu;  ventral  sutures  are 
straight  in  most  species,  but  the  third  and  fourth  are  slightly  curved  in  A^ 
conjnnctuH,  which  thus  shows  a  tendency  towards  Tychius.  The  claws  are 
usually  cleft,  or  armed  with  a  long  slender  tooth;  in  certain  species,  as  will 
be  .seen  in  the  followinir  table,  the  tooth  is  broad,  or  even  so  obtuse  as  to 
be  indistinct.  The  funicle  of  the  antennaj  is  usually  7-jointed,  but  in  the 
sj)ecies  of  Division  C  only  six  joints  are  observed. 

These  characters  seem  to  be  similar  to  those  used  by  Lacordaire  for  sep- 
arating the  genera  of -4?i</K>/w»HVii",  (Gen.  Col.  VI,  577),  but  on  referring 
to  the  detailed  descriptions,  it  will  be  found  that  in  other  respects  the  spe- 
cies in  our  fauna  disagree.  I,  therefore,  deem  it  more  expedient  to  place 
them  all  in  Anthonomus.  The  following  table  will  enable  most  of  them  to 
be  easily  recognized.

The  color  is  black,  with  the  antennae  and  tarsi  testaceous;  the  front 
thighs  are  armed  with  a  very  small  tooth,  and  the  others  are  entirely  un- 
armed. The  markings  are  composed  of  scales,  and  in  well  preserved  spe- 
cimens the  sides  of  the  prothorax  and  the  trunk  arc  also  scjuaniose;  a  small 
post  scutellar  line  and  another  each  side  at  the  base,  and  an  indistinct  pro- 
thoracic  dorsal  line  arc  also  whitish.  The  elytral  markini^s  stop  suddenly 
at  the  eighth  strisc,  along  which  the  front  marijin  of  the  curve  is  prolonged, 
thus  giving  an  oblique  outline.  The  color  varies  and  tliL  elytra  and  legs 
are  sometimes  dark  brown.  I  am  in  doubt  whether  tiiis  species  is  properly 
identified  with  the  one  intended  by  Gyllcnluil.  If  tW.  latter  be  not  the  one 
licre  described,  it  is  probably  nothing  more  than  a  dark  variety  of  the  nc.\t 
species,  A.  suhguttatus,  described  below,  also  agrees  moderately  well,  but 
the  elytra  are  not  piceous  and  the  beak  is  not  striate.  If  on  examining  the 
original  tj'pe  of  sciitelkitiis  it  is  found  that  this  species  is  distinct,  it  may 
be  called  variegatim.

Atlantic  slope;  found  also  hj  Mr.  Crotch  at  San  Diego  and  San  Bernar- 
dino, California. 

A  small  yellowish-brown  insect,  densely  clothed  with  yellow  pubescence, 
with  a  large  dark  spot  near  the  base  and  another  transverse  one  beJiind  the 
middle,  connected  by  a  suturul  stripe;  sometimes  there  is  an  appearance  Oi" 
a  third  spot  near  the  tij)  of  the  elytra. 

This  insect  might  be  easily  confounded  with  some  of  the  varieties  of 
Phyllotrox  nubifcr,  but  the  elytra  are  less  broadly  nunded  at  tip,  and  the 
claws  are  not  simi)le,  but  broadly  appendieulate.  It  varies  greatly  in  size, 
1.8-2.9  mm.;  .07-.11  inch.  Bred  by  Mr.  Walsh  from  a  CecidomyidouB 
gall;  S.  brasaicoides  of  tialix  lonyifolia. 

Tribe  X.  PRio^roMKRlMi. 

This  tribe  contains  a  few  small  species  of  robust  form,  easily  known  X^y 
the  following  assemblage  of  characters  : 

Beak  stout,  sometimes  short  and  flat:  antcnnai  inserted  about  the  middle, 
scape  extending  upon  the  eyes  which  are  large  and  rounded  ;  funicle 
7-jointed,  club  very  large,  pubescent,  oval  pointed,  almost  articulated. 
Protbora.v  without  postocular  lobes,  front  coxte  contiguous;  prosternum 
short,  not  emarginate. 

Ventral  sutures  deeply  impressed;  the  first  is  straight,  the  others  strongly 
angulated  at  the  sides;  fifth  segment  scarcely  longer  than  the  fourth.    Legs 
stout,  tibiie  with  a  slender  terminal  hook  ;  tarsi  dilated,  spongj'  beneath  ; 
third  joint  bilobed,  claws  appendieulate,    Pygidium  more  or  less  visible. 
Beak  as  long  as  prothora.K.  sub-cylindrical;  long;  front

less  interrupted  on  the  seventh  interspace,  which  attains  the  suture  about 
one-fourth  from  the  tip ;  striie  jiunctured,  less  deep  than  in  P.  scutsllaris. 
Thighs  armed  with  a  small  acute  tooth ;  claws  appendiculate.  Length 
2.5  mm.;  .10  inch. 

Georgia;  one  specimen.  The  large  C(mimon  spot  of  the  elytra  is  dark 
only  at  the  edge,  in  the  middle  it  is  nearly  as  pale  as  the  ground  color.  A 
manuscript  drawing  by  my  father  named  Arhynchus  to)nentom3\  Da]. 
Cat.  resembles  this  species. 

Tribe  XI.  tychiim. 

In  this  tribe  a  form  of  body  is  resumed,  wliich  resembles  ihat  of  the 
Erirhinini.  The  claws,  however,  are  not  simple,  but  appendiculate  or 
toothed,  and  the  second,  third  and  fourth  ventral  sutures  are  not  straight, 
but  strongly  angulated  at  the  sides.  The  prolongation  backwards  of  the 
side  angles  of  the  second  segment  is  in  some  genera  carried  to  such  an 
extent  that  the  points  reach  the  fourth  segment,  and  the  sides  of  the  third 
segment  are  thus  entirely  covered.  The  pygidium  is  usually  exposed, 
by  the  tips  of  the  elytra  being  separately  rounded,  but  in  I'ychitis  they  are 
conjointly  rounded,  and  the  lygidium  is  covered.  This  character,  as  in 
Anthonomini,  possesses,  there ibrc,  but  little  value.  The  ventral  segments 
are  less  unequal  than  in  Erirhinini. 

The  other  cliaracters  are  those  common  to  the  preceding  tribes ;  Beak 
long  and  usually  slender;  antenufe  inserted  far  from  the  tip;  antcnnal 
grooves  direcied  sometimes  against  the  eyes,  sometimes  below  them. 
Th(!  eyes  are  rouniied  or  nearly  so,  not  finely  granulated.  The  funicle 
of  the  antenna'  is  6-  or  7-joiiited,  and  the  club  entirely  pubescent  and 
annulated.  The  prothorax  has  no  postocu'.:r  lobes;  the  prosternum  is  short, 
not  strongly  emarginate  in  front,  and  the  eoxoj  are  contiguous.  Tiie  side 
riieces  of  \\\c  mesotliorax  are  diagonally  dividtjd,  and  the  epimera  do  not 
largely  attain  the  base  of  the  luothorax.  Th-.:  metasternum  is  long,  and  the 
Kide  pieces  are  narrow,  or  moderately  •'vide,  dilated  in  front.  Tibiie  feebly 
or  strongh'  nnicronatj;  articular  surOvi  >rolonged  on  the  outer  face,  so  as 
to  bectuie  oblique. 

Our  genera  with  three  exceptions  have  not  been  described: 

Angles  of  second  ventral  segment  not  extending  to  the  fourth 2.

PROCTORUS  n.  g. 

This  new  genus  is  established  upon  a  small  insect  whicli  has  altogether 
the  form,  sculpture,  and  mottled  pubescence  of  Erirhinus;  it  is,  however, 
easily  known  by  the  stouter  beak,  the  curved  ventral  sutures,  and  the 
broadly  appcndiculate  claws.  The  se.xual  characters  of  the  -^  are  very  re- 
markable; the  fifth  ventral,  namely,  i.s  a.s  long  as  the  three  preceding  uni- 
ted; it  is  divided  by  a  transverse  sharply  elevated  ridge  into  two  jiarts,  of 
which  the  anterior  is  the  larger  and  broadly  concavtr,  the  binder  part  is 
much  more  deeply  concave,  and  on  taoh  side  atthi^  jnnoi  j'-'!1  of  lite  elevated 
ridge  with  the  margin  is  a  stout,  tlattcned  horn,  voundcii  .it  the  tip;  on  the 
anterior  margin  of  the  segment,  at  the  middle,  i.s  a  third  .shorter  horn. 

Beak  as  long  as  theprothorax,  rather  stout,  cylindrical,  somewhat  curved, 
densely  punctured,  not  striate  nor  carinate.  Antenuic  inserted  about  one-

are  rounded  and  distant;  funicle  7-jointed;  first  joint  as  long  as  the  two 
following,  and  stouter;  2-7  short,  equal,  gradually  a  little  wider;  club 
moderate  in  size,  elongate-oval,  subacute,  anuulated;  ante.unal  grooves 
reaching  the  lower  margin  of  the  eyes.  Prothorax  about  as  wide  as  long, 
rounded  on  the  sides  in  front,  and  feebly  ■nipressed  near  the  tip.  J^lytra 
wider  at  base  than  i)rothorax,  elongate  oblong,  humeri  prominent,  rounded, 
sides  parallel;  marginal  stria  incomplete  at  the  nnddle.  Ventral  segments 
unequal;  third  and  fourth  together  scarcely  longer  than  each  of  the  others; 
first  suture  straight  at  the  sides,  arched  forwards  at  the  middle;  otlior  su-

ENCALUS  n.  g. 

This  genus  also  resembles  a  small  Erirhinus,  and  differs  from  Proetorun 
only  by  the  beak  being  longer  than  the  prothorax,  and  more  slender;  it  is 
also  punctured  and  feebly  striate  towards  the  base,  as  in  many  Anthonomi. 
The  antennae  are  inserted  about  one-fourth  from  the  end  of  the  beak;  the 
scape  almost  reaches  to  the  eyes,  which  are  moderate  in  size  and  distant: 
the  funiculus  is  7-jointed,  first  joint  longer,  the  others  nearly  equal,  short, 
gradually  wider  and  more  rounded;  club  oval,  annulated;  ventral  segments 
unequal,  third  and  fourth  together  as  long  as  second,  fifth  nearly  as  long; 
first  suture  straight;  others  angulated  at  the  sides.  Legs  moderate,  thighs 
armed  with  a  small  tooth;  claws  divergent,  broadly  ajipendiculate. 

I.E.  decipiens  n.  sp. 

Tilack,  clothed  with  white  and  yellowish  pubescence.  Prothorax  not

suture  is  velvety  black,  contrasting  well  with  the  diftused  brown  tint  into 
Avhich  the  band  fades  towards  the  tip  of  the  elytra.

TYOHIUS  Sch. 

The  few  species  of  this  genus  thus  far  known  in  our  fauna  have  the  funic- 
ulus of  the  antenna)  7-jointed,  with  the  exception  of  7'.  setosm,  which 
may  perhaps  be  hereafter  recognized  as  generically  distinct;  they  resemble 
in  form  Ventrinus,  though  the  contiguous  front  coxffi  and  toothed  claws  will 
enable  them  to  be  immediately  distinguished. 

It  is  worthy  of  remark  that  the  first  observation  concerning  the  anal  seg- 
ment of  the  ^,  is  recorded  by  Mr.  Brisout  de  Barneville.*  Had  the  impor- 
tance of  this  observation  been  recognized,  and  its  limitations  inquired  into, 
much  of  the  labor  1  have  devoted  to  the  study  of  the  llhynchoi)horous  series 
would  have  been  saved,  and  our  knowledge  concerning  the  classitieation  of 
these  insects  would  be  much  farther  advanced,  f 

Our  species  may  be  thus  distinguished  :

Two  specimens,  Illinois  ;  Mr.  Walsh.  Say  apparently  confounded  this 
species  with  tiie  one  described  by  liim  as  T.  aratus;  and  Major  Gylh^nhal 
suspecting  perhaps  the  existence  of  some  error  has,  while  quoting  Say  in 
synonymy,  given  a  different  name  to  the  insect  received  from  that  author. 
Although  of  the  size  (3.3  mm.;  .13  inch)  and  form  as  T.  anitm,  it  is 
quite  distinct  by  the  beak  narrowed  from  the  base  to  the  tip,  less  distinctly 
channeled,  and  more  densely  pubescent;  the  covering  Is  of  fine  narrow 
prostrate  hair-like  scjiles  of  a  uniforni  pale  dirt  color,  and  the  hind  thighs 
are  distinctly  toothed.    1'.  aratus  is  unknown  to  me,  unless  it  be  T.  tectus.

scales  of  the  under  surface  are  broader  than  those  of  the  upper  surface.  The 
teeth  of  the  claws  are  more  approximate  than  in  the  foregoing  species.  The 
scales  of  the  prothorax  converge  backwards,  as  described  by  Say,  but  the

PARAQOGES  n.  g. 

A  curious  little  species  from  California  constitutes  this  genus.  Tt  has  all 
the  essential  characters  of  Tj/rhiua,  ex(H>pt  that  the  pygidium  is  somewhat 
cxi)osed,  and  the  claws  are  small,  sin\ple  and  api)roximate.  The  beak  is 
longer  than  the  prothorax,  cylindrical,  nearly  straight,  and  rather  slender. 
The  antennal  grooves  descend  obli(]Uely  below  the  eyes,  which  are  small, 
rounded,  and  coarsely  granulated.  The  funicle  is  (l-jointed;  first  and  second 
joints  longer,  the  first  being  stouter;  :?-()  gradually  a  little  broader,  some- 
what rounded;  club  oval-pointed,  pubescent,  annulated.  Protliorax  as  long 
as  wide,  constricted  near  the  tip,  without  jiostocidar  lobes.  Ely'ra  oblong 
elongate,  wider  than  the  prothorax,  separately  rounded  at  tip.  A.igles  of 
second  ventral  segment  prolonged  as  far  as  the  fourth  segment.  Legs  mod- 
crate,  thighs  not  toothed;  tibia'  oblicpiely  truncate  at  tip,  scarcely  i)ercep- 
tibly  mucronate;  tarsi  spongy  beneath,  third  joint  broader,  bilobed;  claws 
small,  sim]»le,  not  divergent.

Tribe  XIL    ciosfixi. 

In  this  tribe  the  funicle  of  the  antenme  has  but  five  joints;  tlie  club  is

Tribe  XIII.     OEREl.oimxi. 

A  tribe  whicli  contains  a  few  small  species  of  oblong  elongate  form, 
glabrous,  and  fetibly  punctured,  with  the  hind  angles  of  the  prothorax  rect- 
angular and  better  detined  than  usual.  The  beak  is  slender,  long,  cylin- 
drical, and  is  usually  projected  forwards;  it  can,  at  most,  be  bent  perpendicu- 
larly downwards  in  rejOTSc;  the  antennal  grooves  descend  oblif|ucly  to  the 
lower  edge  of  the  eyes,  which  are  moderate  in  size,  nearly  rovind,  coarsely 
granulated  and  distant  from  the  prothorax.  The  antenna',  inserted  one-fourth 
from  the  tip,  are  slender,  the  scape  reaches  the  eyes;  the  fvmicle  is  7- 
jointed;  first  joint  stouter,  and  as  long  as  the  two  following  united;  the  second 
and  the  succeeding  ones  become  slightly  broader,  rather  closely  connected 
and  merge  into  the  club,  which  is  pubescent,  elongate,  pointed,  and  strongly 
annulated.  The  prothorax  is  quadrate  for  the  greater  part,  then  suddenly  nar- 
rowed to  the  tip,  which  is  constricted;  near  the  tip  there  is  a  short,  acute 
oblique  lateral  ridge  representing  a  part  of  what  is  the  lateral  margin  of  the 
pronotum  in  other  Coleoptera.  The  prosternum  is  very  long  in  front  of  the 
coxic,  which  are  nearly  contiguous  in  our  species,  though  distinctly  sepa- 
rated in  the  foreign  genera;  it  is  not  emarginate  in  front,  and  the  prosternal 
sutures  are  o])literated.  The  elytra  are  scarcely  wider  than  the  prothorax, 
parallel  on  the  sides,  conjointly  rounded  behind,  so  as  to  cover  the  pygid- 
ium;  the  surface  is  punctulatc,  and  the  striic  are  obsolete.  The  middle 
coxie  are  moderately  separated;  the  side  pieces  are  diagonally  divided,  and 
the  epimera  attain  widely  the  base  of  the  prothorax  beneath,  though  they 
do  not  intervene  between  the  elytra  and  the  pronotum.  Metasternum  mod- 
erately long,  side  pieces  narrow,  widei  in  front.  First,  second,  and  tifth 
ventral  segments  long;  third  and  fourth  united  about  equal  to  each  of  them; 
surface  rather  fiat,  sutures  fine  and  wel'  >  'j  -cssed,  nearly  straight;  second 
suture  slightly  curved  at  the  sides;  in  viic  f j  ,  the  anal  segment  is  slightly 
visible  at  the  tip  of  the  fifth  ventral.  Legs  rather  stout,  thighs  compressed

Tribe  XIV.     i.iKMONACCIlvI. 

This  tribe  is  composed  of  a  sintrle  f^enus  Jj(Pmof(treuii,  of  which  one 
species  occuis  in  our  Southern  Stales.  It  is  easily  known  by  the  exposed 
pygidiuni;  llie  larije,  prominent  and  distant  fnmt  oo,xiu,  and  the  breast  not 
channeled.  The  side  iiieces  of  th(?  niesothorax  are  very  transverse,  and  in- 
tervene somewhat  between  the  prolborax  and  elytra;  the  epistenia  of  the 
metathonix  are  wide,  and  the  epiniera  are  visible  behind.  The  ventral  su- 
tures are  stniiuht;  first  and  second  setrmenls  ecpial,  lonj;er  than  the  third 
and  fourth.  The  lej;s  are  stout  and  short,  iuul  the  tiliia'  art'  strongly  iiooked 
at  tij);  tlie  tarsi  are  dilated,  and  the  last  jointis  very  slender,  with  two  very 
small,  simple  claws. 

The  beak  is  short,  stout  and  cylindrical;  the  antennal  jjjrooves  extend  to 
the  lower  margin  of  the  (.'yes,  which  are  oval  and  transverse.  The  antennic 
are  inserted  about  the  middle,  and  are  scarcely  geniculaled;  the  funicle 
consists  of  seven  joint  and  merges  gradually  into  the  oval,  aniuiliited, 
pubescent  club.  There  is  nothing  jjcctdiar  in  the  mouth;  the  gular  jiedun- 
clc  is  long,  the  tncntum  small,  and  Hit;  palpi  short  and  small;  the  mandi- 
bles are  curved,  and  of  the  usual  form. 

The  allinities  of  this  tribe  seem  to  be  in  the  direction  of  Barini.

more  or  less  covered  by  the  prothoracic  lobes;  and  from  Veutorhynchini  by 
the  pygidium  being  entirely  covered. 

The  pectoral  groove  varies  in  length  according  to  the  group;  the  front 
cosifi  are  contiguous  in  many  species  of  Conolrachelus,  and  other  genera 
of  the  group  Ithypori.  The  side  pieces  of  the  mesothorax  are  obliquely  di- 
vided, and  the  epimera  attain  largely  the  base  of  the  prothorax  on  the 
under  surface,  witliout  intervening  between  the  pronotum  and  the  elytra. 
The  nietasternunl  is  either  long  or  Li.ort;  the  aide  pieces  narrow,  and  di- 
lated in  front.  The  vp'-.iral  segments  vary  in  length;  the  first  suture  is 
straight  or  sinuate,  deep,  or  obliterated;  the  second  and  third  are  some- 
vhet  angulated  at  the  sides.  The  tibiie  are  armed  with  a  strong  hook  at 
the  tip,  and  the  articular  surface  is  oblique;  the  claws  are  simple,  oi 
toothed. 

But  three  groups  are  represented  in  our  fa-  na,  of  which  the  second  is  es- 
tablished upon  a  new  genus.

Pectoral  groove  extending  to  the  mesosternum,  sharply 

limited  behind Cryptorbynchl. 

Group  I.     ItbyporK 

In  this  group  the  pectoral  groove  is  confined  to  the  prosternum,  and  is 
not  closed  behind,  the  mesosternum  is  sometimes  flat,  sometimes  suddenly 
declivous.  The  eyes  are  coarsely  granulated,  partly  covered  in  rejiose  by 
the  protlioracic  lobes,  which  arc  sometimes  very  well  developed,  but  in  other 
genera  are  broad  and  not  prominent. 

Th<!  prothorax  is,  in  most  species,  comparative!)' smaller  than  in  the  other 
groups,  and  usually  very  coarsely  sc\dptured.  Tiie  elytra  tire  wider  than 
the  proihorax,  with  prominent  humeri,  the  outer  stria  is  usuallv  abbre- 
viated, and  there  is  a  tondiMicy  to  an  epipleural  fold.  The  thiglis  are 
toothed  in  our  genera;  the  liliiic  slender,  hooked  at  the  tip;  the  claws 
usually  toothed,  though  sometinu's  simple,  or  even  connate  at  the  base. 

The  front  coxte  are  sometimes  contiguous,  a  character  not  observed  in  the 
other  g'.oups  of  this  tribe.

OONOTRACHELUS  Sch. 

This  g(  mis  contains  some  of  the  most  formichihlc  enemies  of  our  culti- 
vated fruity,  especially  the  stone  fruits,  such  as  tlie  plum,  apricot,  itc. 

They  are  easily  recognized  hy  the  cliaracters  given  above,  to  whicli  maj' 
he  added  t!»e  following,  which  serve  t  j  distinguish  this  from  some  foreign 
genera;  the  antennal  grooves  are  not  confluent  behind,  and  the  hind  thighs 
are  not  pedunculated.  , 

A  sinsxuliir  thougii  harmless  error  has  been  committed  by  Schonherr  and 
Ilia  colJaliorators  in  describing  the  antenuic  of  most  of  the  species  as  "longe 
pone  medium  rostri  sita-."  Geometrically  this  is  correct,  as  the  rostrui ' 
when  not  used  in  feeding,  or  in  its  equally  legitimate  occupation  as  ovipos- 
itor, is  inllexed  upon  the  breast,  and  directed  backwards;  its  tip  is  there- 
fore in  that  position  the  pos'.'U'iwr  extremity.  ^lorpliologically,  however, 
the  beak  being  an  extension  of  the  longitudinal  axis  of  tiie  body,  the  tip  is 
the  anterior  extremity;  the  word  pone  in  the  description  should  therefore 
liave  been  ultra.  The  insertion  of  the  antenufc  behind  the  middle  of  the 
beak  probably  does  not  occur  in  this  tribe,  or  group,  though  in  some  of  the 
long  beaked  species  of  this  genus  (Nos.  11-13,)  they  attain  nearly  that  po- 
sition. 

The  species  indicate  the  following  divisions : 

Claws  divergent,  toothed 2 

"    approximate,  deft,  (as  in  Anthonoiniin) , .       3. 

2.  Prothorax  not  sulcate,  usually  carinate 1, 

(A.  J^lytnxl  costic  intermixed;  thighs  bidentate  : 
15.           "      entire,  or  absent,  thighs  unidfsntate). 
Prothorax  broadly  sulcate,  with  two  cn^sts  in  front II. 

3.  Pubisccnce  i)ro8trate,  fine III.

As  these  ilivisions  reciuire  fuller  definitions,  the  synoptic  table  of  the 
species  will  be  found  under  each. 

Division  I— A.  Sp.  1-9. 

Tlie  s]ief  ies  of  this  division  an;  related  to  C.  nenuphir,  and  agree  with 
it  in  liavinii-  the  costie  of  Mie  third  and  fifth  interspaces  of  tin;  elytra  more 
or  less  inl(rru])ted  in  two  places.  Tiie  prothorax  is  not  sulcate,  but  .isually 
distinctly  carinate,  and  strongly  constricted  near  the  tip;  the  thiglis  are  bi- 
dentate. Tlicfie  characters,  except  .he  last,  are  evanescent  in  T.  niroKUt, 
which  shows  a  passage  to  Division  II,  and  appean  closely  allied  lo  C. 
leuMpJurdtiix. 

The  pulu'scencc  is  short,  line  and  appressed;  it  forms  a  mnn-  or  less  com- 
plex pattern  of  slender  pale  lines  each  side  of  the  prothorax,  and  a  broad 
hand  behind  the  middle  of  the  elytra.  In  well  preserved  specimens  the 
color  auil  ili-trilnition  of  tin'  pubescciu-p  afford  o:isy  cliaracters  for  the  recog 
nition  of  the  species;  hut  otiierwise,  they  arc  closely  allied,  and  reciuirc 
care  in  their  separation.

Middle  States,  on  walnut.  This  species  is  closely  allied  to  the  i)luni

crest  of  the  fifth  elytral  Interspace  is  longer,  almost  as  large  as  that  of  the 
third,  and  overlaps  It  far  more  than  half  its  length,  and  finally  the  pubes- 
cence is  of  a  nearly  uniform  color,  so  that  the  band  of  the  elytra  is  not 
variegated  with  white.  The  ventral  segments  are  much  less  densely  ))unc-

Found  over  the  Atlantic  slope,  wherever  the  plum  is  cultivated  or  native. 
It  attacks  also  other  stone  fruit,  and  is  said  to  infest  apples,  pears  and 
quinces  (Harris  loc.  cit).  Furtlierol)scrvations  on  this  point  are  desinible,  as 
it  is  very  unlikely  that  such  different  plants  are  attacked  by  the  same  species. 
The  crests  of  the  elytra  are  more  abrupt,  and  the  posterior  ones  more  promi 
nent  than  in  the  two  preceding;  the  second  elevation  of  the  fifth  interspace  in 
front  of  the  middle  is  conspicuously  smaller  than  that  of  the  third  inter- 
space, and  does  not  overlap  it  as  much  as  in  C.  juglandis.  Tlie  elytral  l)and 
is  composed  of  yellow  and  white  hair;  there  is  a  conspicuous  white  lino  at 
the  base  of  the  third  interspace.  The  thorax  is  longer  and  less  rounded  on 
the  sides,  than  in  the  two  preceding.  The  beak  is  stout,  curved,  and 
strongly  striate  and  punctured;  the  ventral  segments  coarsely  and  densely 
punctured;  fifth  with  two  setigerous  tubercles;  I  liave  many  specimens

Division  I— B.  Sp.  10-18. 

The  species  of  this  division  differ  from  the  preceding,  chiefly  by  the  al- 
ternate interspaces  of  the  elytra  bein'i;  elevated,  and  not  interrupted  into 
short,  abrupt  crests;  the  inner  one  (of  luc  third  interspace)  is  in  <nery  case 
entire.  In  other  respects  they  resemble  those  of  the  i)receding  division  in 
several  important  characters;  the  prothorax  is  more  or  less  carinate,  not 
grooved;  the  surface  is  finely  pubescent,  with,  at  most,  lines  of  very  sliort 
bristles  on  the  elytra.  On  the  other  hand,  the  thighs  are  armed  with  a 
single,  usually  acute  tooth,  without  a  trace  of  the  second  tooth  or  denticle.

New  York,  Georgia,  Illinois.     The  form  is  broader  and  more  squat  than 

in  any  other  of  our  species,  and  it  is  easily  distinguished  by  the  Inimeri 
being  obliquely  truncate,  with  the  outer  angle  dentiform;  this  appearance 
is  produced  by  a  sliort  carina  between  the  third  and  fourth  elevated  ridge 
of  the  elytra,  which  meets  the  fourth  ridge  at  an  acute  angle.  The  beak  is 
punctured  and  very  deeply  striate;  head  densely  punctured;  protliorax 
carinate,  elevated  at  the  middle,  broadly  transversely  impressed  in  front, 
densely  and  finely  cinereous  pubescent,  with  an  indistinct  pattern  of  paler 
pubescence  each  side,  meeting  in  front  of  the  middle.  The  elytra  are 
clothed  with  dirt-colored,  slightly  mottled,  fine  pubescence,  with  rows  of 
short,  whitish  setie;  the  third,  fifth,  seventh  and  ninth  interspaces  are 
strongly  carinate,  leaving  broad  furrows,  each  marked  with  two  rows  of 
quadrate  punctures.  The  body  beneath  is  tliinly  clothed  with  yellowish 
pubescence,  sparsely  punctured  and  cribrate;  the  third  and  fourth  ventral 
segments  still  more  sparsely,  and  the  fifth  rather  densely  punctured.  Thighs 
armed  with  a  large,  not  very  acute  tooth.  The  middle  coxte  are  more 
widely  separated  than  in  tlie  other  species.     Length  5  mm.;  .20  incli. 

The  beak  of  the  female  is  a  little  longer  and  less  deeply  striate  than  in  the 
male;  the  last  ventral  segment  in  both  sexes  is  foveateeach  side,  and  feebly 
impressed  at  the  middle  near  the  tip;  but  these  impressions  are  broader  in 
the  female.

Kansas,  Mr.  E.  A.  Popinoe,  one  specimen.  The  rows  of  punctures  of  the 
elytra,  from  tlie  absence  of  pubescence,  appear  black;  the  white  dots  oc- 
cupy the  distance  between  them,  and  contrast  elegantly  with  the  yellow 
pubescence  of  the  main  surface.  The  white  lines  of  the  prothorax  are  nar- 
row, and  not  very  conspicuous;  they  converge  but  scarcely  meet  at  the 
front,  and  are  sliglitly  curved;  the  middle  carina  is  also  clothed  beliind  with 
white  hair;  the  scutellum  and  a  small  spot  at  the  base  of  the  third  inter- 
space of  the  elytra  are  also  white.

In  this  division  the  form  is  rather  squat,  the  elytra  at  base  being  nearly 
twicu  as  wide  as  the  prothorax;  the  latter  is  coarsely  sculptured,  and  has 
two  crests  in  front  of  the  middle,  between  which  is  a  wide  furrow.  The 
beak  is  curved,  a  little  longer  than  the  head  and  prothora.\,  strongly  punc-

RHYSSEMATUS  Sch. 

Concerning  this  genus  I  have  little  to  add  to  the  excellent  synoptic  table 
and  remarks  published  by  Dr.  Horn,  (Proc.  Am.  Phil.  Soc.  1873,  463) 
except  that  the  ditlerences  between  it  and  Ghalcodermus  as  stated  by  La- 
cordaire  are  somewhat  illusive;  the  corbels  of  the  hind  tibiie  seem  in  some 
specimens  of  11.  litutiticollU  to  be  (luite  distinct.  On  the  other  hand,  there 
is  a  great  ditference  in  the  form  of  the  claws,  which  in  Rhy»iiematu»  are 
cleft  as  in  AiUhoiwmiiH,  but  in  ChnlcodermuH  are  approximate  and  connate 
at  base,  almost  as  in  iSmieronyx,  &c.  There  is  also  an  important  difference 
in  the  two  outer  striic  of  the  elytra,  which  are  separated  by  a  costa  in  the 
first,  just  as  in  ConolracMuH,  but  in  the  latter  the  outer  strife  consists  of 
only  a  few  large  punctures  extending  one-third  the  length  from  the  base, 
and  the  interspace  is  flat. 

In  view  of  the  importance  of  these  characters  it  becomes  necessary  to 
place  C'halcodermuH  pruinosia  Boh.,  (Sch.  Cure,  viii,  2nd,  13)  in  this  genus; 
from  the  other  si)e(;ies  it  is  easily  distinguished  by  the  less  rugose  punctua- 
tion of  the  prothorax. 

OHALCODERMUS  Sch. 

The  remarks  of  Dr.  Horn  upon  the  three  species  of  this  genus  which  re- 
main after  removing  C.  pruinosus  leave  nothing  to  be  added.

1.  Z.  sulcatus,  n.  sp. 

Dark  reddish  ))rown;  head  and  tubular  constriction  of  protliorax  smooth,

pilose  witli  long,  erect  wliitish  hairs.  Elytra  deeply  sulcate,  grooves  ])une-

from  scarcely  perccptilile  punctures.     Length  l.Hmm.;  .07  inch. 

One  specimen,  Pennsylvania;  .Mr.  8.  S.  K;itlivon.  The  essential  dill'er- 
ence  between  this  and  the  preceding  is  in  the  elytral  sculpture.  The  other 
characters  are  dependent  on  sex,  and  on  better  preservation  of  the  speci- 
men.

lus of  tlie  antenuic  and  the  simple,  divergent  claws.  Tlie  beak  is  shorter

Two  specimens,  Georgia. 

Group  n.     Acampti. 

As  Qunptorhinus  diflera  from  the  Cryptorhynchi  by  the  pectoral  groove 
being  confined  to  the  i)rosternum,  though  distinctly  limited  behind,  so  is 
the  singular  insect  which  constitutes  this  group  similarly'  separated  from 
the  Ilhypori,  by  the  shorter  beak  resting  upon  the  front  coxiu.  The  body 
is  elongate,  as  in  Camptorhinns,  and  the  tibiie  are  stout,  sinuate  on  the 
inner  side,  and  strongly  hooked  at  th(!  tip.  The  other  characters  are  pecu- 
liar, the  tarsi  are  not  dilated  nor  spongy  beneath,  and  the  clul)  of  the  an- 
tenna' is  pubescent  and  sensitive  only  near  the  tip. 

These  characters  indicate  relationships  in  various  directions,  such  as  the 
Byi'nopidir,  and  Gosiaonidm,  but  the  insect  preserves  unchanged  all  the  es- 
sential characters  of  the  Cryptorhynch  type  of  Curculionidm. 

AOAMPTUS  n.  g. 

A  very  singular  species  of  elongate  form,  clothed  with  dirt-colored  hair, 
and  short,  ere(;t  bristles  represents  this  genus. 

The  beak  is  short  and  stout,  as  long  as  the  head,  and  expanding  grad- 
ually into  it,  so  that  no  distinct  separation  appears;  the  antennal  grooves 
begin  al)out  one-third  from  the  end,  and  descend  obliipiely  to  the  eyes, 
which  are  small,  lateral,  and  not  prominent.  Aniennie  with  the  scape  ex-

by  my  father,  it  is  Botrobatys  trof/lodi/tes \l)ci.  Cat. 

Group  in.     i'ryptorhynchl. 

In  this  group  the  pectoral  groove  is  distinctly  limited  behind.  The  other 
characters  are  variable,  though  the  front  coxie  are  never  contiguous  as  in 
some  Ithypnri;  a  slight  api>eanince  of  an  epii)leunil  fold  exists  in  many 
species.  Tlu!  claws  are  toothed  in  Phyrdenas,  but  8imj)le,  and  generally 
small  in  the  other  genera. 

The  genera  in  o'.ir  fauna  are  not  numerous,  but  present  several  categories 
indicating  sub-groups,  which  it  is  iuineees.sary  to  define  at  present,  as  their 
number  would  be  increased  liy  a  careful  study  of  exotic  forms.  Mirrom(istn$ 
might  be  placed  witheipial  propriety  in  llhypori,  iwar  Art/iroslc.nns,  but  for 
the  present  I  prefer  as.sociating  it  with  Addles:  the  only  specimen  in  my

The  very  short  metastcrnum,  with  indistinct  episterna,  the  oval  eiytra 
with  rounded  sides,  and  the  small  tarsal  claws  will  enable  the  species  of

the  base,  much  narrr)wed  in  front,  and  broadly  constricted;  disc  densely 
jmnctured,  stron<2;ly  carinate,  marked  with  a  short,  transverse  wliitc  line  at 
the  middle,  interrupted  at  tin?  dorsal  line;  the  parts  of  this  transverse  line

Enterprise,   Floritla;  Messrs.  llubliard  and  Srhwurz;  found  also  in  lUi 

nois.  This  small  species  is  thickly  clothed  with  brown  scales,  and  l)Ut 
slightly  varied  in  color;  there  are,  however,  two  interrupted  liandscomi)osed 
of  small  white  siM)t8  on  the  elytra;  the  striiu  are  composed  of  large,  tjuadrate 
punctures;  the  interspaces  are  wide,  slightly  convex  and  furnished  with 
rows  of  long,  clavate  bristles.  The  prothorax  is  very  coarsely  punctured, 
not  carinate,  and  the  bristles  are  a  little  shorter  than  upon  the  elytra. 
Length  2.5  mm.;  .10  inch. 

The  female  is  .^louter  than  the  male,  with  the  prothorax  not  much  wider 
at  the  middle,  and  the  elytra  much  more  rounded  on  the  sides. 

I  have  received  from  Col.  ^lotschulsky  a  specimen  from  New  Orleans, 
which  seems  quite  similar,  «\xcepl  that  the  punctures  of  the  elytral  stri«5 
lire  so  large  that  the  interspaces  lieeome  very  narrow.  I  am  disposed  to  be- 
lieve that  this  appearance  is  ow  iiig  to  jiartial  abrasion  of  the  scales.  If, 
however,  with  a  larger  series  of  specimens,  il  should  be  found  to  be  really 
distinct,  the  name  A.  ni'dhrosm  Motsch.  will  be  retained  for  il.

The  species  fall  naturally  into  two  divisions  already  indicated  liy  Dr. 
Horn,  Froc.  Am.  Ent.  Soc.  187:J,  407;  the  first  contains  the  type  of  Tj/l'.- 
deniKi,  the  ,-rcontl  that  of  Aiiiilcix;  I  hiwc,  therefore,  restored  the  former 
name  to  the  conjoined  genus. 

Division  I. 

In  the  lirsl  division  the  color  is  not  metallic;  the  i)ultcscence  is  in  distinct 
spots,  and  sometimes  scaly;  the  abdomen  is  coarsely  punctured,  and  the 
punctures  of  the  elytra  are  large.  These  species  resemble  in  appearance 
Mwm<irle»,  but  dilfer  very  greatly  in  structural  characters. 

I  have  nothing  to  add  to  the  character-;  of  the  four  species  of  this  group, 
as  given  by  Dr.  Horn,  but  to  say  that  7'.  foveolutuiu  varies  greatly  in  size, 
some  sjiecinunislicing  no  larger  than  7'.  rnricgdhun,  from  which  it  is  at  once 
distinguished  by  the  fovcate  rather  than  punctate  prothorax.

for  which  r  have  adopte(]  the  Caialogui'  name  of  Dejean.  If  our  fauna  had

BAROPSIS   n.g. 

The  single  species  for  which  I  propose;  this  generic  name,  agrees  with 
the  two  preceding  genera  in  most  characters,  but  ditfers  essentially  in  the 
first  ventral  suture  being  more  distinctly  sinuate,  and  nearly  obliterated 
at  the  middle,  and  the  sei'ond  ventral  segment  as  long  as  the  two  follow 
ing  united.  The  licak  is  nearly  us  stout  as  in  Tylodenmi,  and  the  eyes 
are  approximate  above;  the  funicle  of  the  antenme  is  slender,  7  jointed,  the 
second  joint  as  long  as  the  first;  the  following  are  shorter,  but  not  nnn'h 
thickened;  club  small,  oval-acuminate,  annulated.  Legs  not  very  stout, 
thighs  feebly  clavate,  armed  with  a  small  acute  tooth:  tibia' moderately  c(»m- 
pressed,  not  as  wide  as  in  the  two  preceding  genera,  not  toothed,  ternunal 
liook  small;  there  is  a  fringe  of  hair  on  the  outer  margin  towards  the  tip. 
as  in  C'alosternns. 

The  general  ap|)earance  is  that  of  Tylodtnuu,  but  the  sculpture  roseni 
hies  that  of  sev'-nil  species  of  liurlt.     It  is  closely  related  to  the  Mexican

Tile  I'orm  of  these  insects  is  (|uitc  peculiar;  the  body  is  elongate,  sub- 
riiomlioidai,  the  liist  and  second  ventral  segnients  long,  tlie  remaining  ones 
short,  rarely  horizontal,  as  in  the  preceding  genera,  but  forming  an 
obli(piely  ascending  surtiice.  The  pygidium  is  loncealed  by  the  elytra  in 
our  species,  lail  is  visible  in  some  foreign  genera,  The  eyes  are  large,  and 
not  concealed,  even  when  the  head  is  detlexed;  they  are  closely  approxi- 
mati-  on  the  front,  but  widely  distant  beneath  and  linely  granulated.  The 
lieak  is  long  ;ind  slender,  only  slightly  curved,  and  is  received  in  a  deep 
pro>ternal  canal,  which  in  some  species  does  not  extend  upon  the  meso- 
sternum,  so  that  'he  end  of  the  beak  is  free,  as  in  ('DiiolriirfiatuH.  evtMi 
when,  as  in  others,  the  mesosicrnum  is  cxiavali'd,  the  canal  is  open  and 
not  sharply  limited  liehind.  Legs  slender,  front  coxii' elongated,  and  pro- 
longitl  into  a  |i<iint  on  the  inner  sidi',  claws  simple,  dixergent.

OOPTURUS  Sch. 

The  species  belonging  to  our  fauna  are  small  and  elongate,  with  the 
elytra  only  a  little  wider  than  the  prothora.x.  They  ditier  from  the  typical 
species  of  tropical  America  by  the  femora  being  not  armed  with  a  tooth. 
We  have  seen  already  in  many  genera  that  this  character  is  quite  unim- 
portant, and  I  consider  it  unworthy  of  even  suiigeneric  distinction. 

Our  si)ecies  nuiy  be  thus  tabulated:

and  not  conspicuous.

This  species  agrees  with  the  preceding  in  form,  color  and  sculpture,  but 
is  very  much  smaller,  the  prothorax  seems  a  little  more  elongate,  and  the 

*  I  have  some  doubts  ns  to  the  specific  difference  l)etween  f.  querciis  and  ail-

coarsely  and  densely  punctured,  clothed  with  large  brown  scales,  and 
sprinkled  with  paler,  with  two  large  basal  spots  of  dirty  white.  Elytra 
with  deep  punctured  stria?,  clothed  with  yellow  and  gray  scales,  with  a 
curved  band,  extending  from  the  humeri  to  behind  the  middle,  then  curv 
ing  forwards  and  meeting  the  suture  at  the  middle,  thus  forming  on  each 
an  oblique  lunule  of  dark  brown.  Beneath  densely  clothed  with  large, 
yellowish  and  grayish  scales,  legs  slightly  speckled  with  dark;  thighs  as  in 
the  other  species,  unarmed.     Length  2..5  mm. ;  .10  inch. 

California;  one  specimen,  collected  by  W.  H.  Pease,  probably  at  Bun 
Francisco. 

9.  O.  minutus.  Eceoptm  minutua  Lee,  Ann.  Lye.  Nat.  New  York,  i,

Easily  knov/n  by  the  small  size  and  different  style  of  coloration,  which  is 
well  represented  in  the  figure  given  by  my  father,  as  above  cited. 

The  beak,  antennae,  legs  and  elytra  are  reddish  brown,  the  latter  with 
deep  stria',  and  lines  of  white  narrow  scales,  forming  a  broad  basal  band, 
an  oblique  band  behind  the  middle,  and  a  narrow  apical  margin;  the  suture 
is  also  white,  but  interrupted  about  the  middle.  Beneath  and  legs  rather 
thinly  clothed  with  narrow  white  scales.  The  head  and  prothorax  are 
darker  than  the  elytra,  the  latter  is  deeply  punctured,  with  a  lateral  vitta 
and  a  small  ante-scutellar  spot  of  white  scales.  The  eyes  are  very  large, 
the  front  extremely  narrow.     Length  2  mm. ;  .08  inch. 

Southern  States.  Differs  from  all  the  preceding  by  the  second  joint  of 
the  funicle  of  the  antennte  not  longer  then  the  third. 

ACOPTUS  n.  g. 

This  genus  differs  from  Uopturus  by  the  ventral  surface  being  nearly 
horizontal,  the  segments  much  less  unequal,  and  the  sutures  nearly  straight, 
as  in  Zygops.  It  is  essentially  difl'erent  from  that  genus  I)y  only  the  first 
joint  of  the  funicle  of  tlie  antenme  being  elongated,  and  b>  the  pygidium 
being  covered  by  the  elytra.  The  mesosternum  is  long,  flat,  and  slightly 
declivous. 

The  second,  third  and  fourth  ventral  segments  are  nearly  equal,  and  the 
fiflh  is  slightly  longer,  and  broadly  impressed  in  the  specimen  examined. 

1.  A.  suturalis,  n.  sp. 

Elongate,  subcylindrical,  black,  sprinkled  with  small  whitish  scales, 
forming  two  very  indefinite  bands  upcm  the  elytra.  Beak  as  hmg  as  the 
prothorax,  cyliinlrical,  curved,  punctured,  slightly  carinate  behind,  without 
scales,  except  at  the  base;  eyes  very  large,  fnrnt  extremely  narrow,  linear; 
liead  clothed  with  scales.  Prothorax  wider  than  long,  slightly  rounded  on 
the  sides,  narrowed  in  front,  where  it  is  broadly  constricted;  densely  punc- 
tured; dorsal  line  elevated,  readiing  neither  base  nor  tip.  Elytra  a  little 
wider  than  the  prothorax,  impressed  near  the  base;  strire  deep,  interspaces 
flat,  densely  punctured;  scales  scattered,  more  condensed  in  two  transverse 
bands,  in  front  and  behind  the  middle;  scutellum  and  sutural  line  as  far  as

New  York;  several  specimens  in  Mr.  Ulke's  collection,  of  which  he  has 
kindly  given  me  one. 

Tribe  XVII.     tavhygoikini. 

This  tribe  contains  a  few  small  species,  which  in  form  and  characters  are 
among  the  strangest  insects  of  the  family.  The  body  is  broadly  ovate,  nitlier 
depressed  above,  and  ornamented  with  tufts  of  hair;  the  prothorax  is  com- 
paratively small,  much  narrowed  in  front.  The  head  is  small,  the  eyes 
large,  and  the  front  very  narrow,  as  in  Zygopini;  the  beak  is  rather  shorl 
and  stout,  as  in  certain  Geutorliynchini,  and  refracted  upon  the  prosternum. 
but  the  antenna?  are  straight,  inserted  near  the  base  of  the  beak,  not  genicu- 
late, and  the  first  joint  (scape),  is  no  longer  than  the  second;  this  is  l()ll(nved 
by  five  short  joints,  gradually  increasing  in  width;  the  club  is  elongate-oval, 
distinctly  annulated.  The  front  coxtc  are  sub-conical,  prominent  and  widely 
separated,  so  as  to  leave  a  space  in  which  the  ))eak  rests  when  retracted. 
The  middle  coxae  are  about  three  times  more  separated  than  the  front  coxa', 
and  the  mesosternum  is  very  short,  transver.se,  and  perpendicul".i  to  I  lie 
general  surface  of  the  metasternuni,  which  is  still  wider.  The  side  p'eces 
of  the  mesosternum  are  large  and  distinct,  those  of  the  metaslernum  are 
narrow.  The  hind  coxtc  are  oval,  more  widely  separated  than  in  any 
other  tribe  known  to  me,  and  near  the  side  margin  of  the  elytra.  The  first 
and  second  ventral  segments  are  very  large  and  connate;  the  third  and 
fourth  very  short;  the  fifth  is  nearly  as  long  as  the  second,  rounded  behind. 
The  pygidium  is  exposed,  and  suddenly  declivous  at  tip,  presenting  tlie  ap- 
pearance of  an  anal  segment  in  both  sexes.  The  front  and  middle  legs  are 
slender  and  moderate  in  lengtli,  the  tibiw  armed  with  a  terminal  hook; 
tlie  third  joint  of  the  tarsi  is  very  widely  dilated,  the  fourth  joint  as  long  a-; 
the  first,  with  divaricate  and  appendiculate  ungues.  The  hind  legs  are 
much  longer  and  stouter,  so  as  to  clasp  the  leaves  upon  which  the  insect 
rests. 

The  geographical  distribution  is  remarkable;  a  few  species  of  Tachygonu* 
in  America;  one  species  of  Binorhopala  in  Birmah.  This  fact,  and  tlie 
extraordinary  characters  above  detailed,  indicate  the  preservation  of  an  an- 
cient form,  which,  although  having  the  affinities  I  have  mentioned,  is 
et^ually  out  of  place  in  any  position  in  a  linear  arrangement. 

TAOHYG-ONUS  Sch. 

The  characters  of  this  genus  are  sufticiently  exposed  in  the  description 
of  the  tribe.     Our  species  are  four,  which  may  be  thus  distinguished: 

A.  Hind  thighs  armed  with  several  long,  acute  spinules  or  teeth;  hind  til» 
ise  flattened  and  curved,  feebly  toothed  on  outer  margin.

Maryland,  southward  to  Texas;  found  on  the  leaves  of  young  oaks,  on 
the  under  surface  of  which  the  insect  sits,  and  falls  to  the  ground  when 
approached,  as  observed  by  Zimmermann.  The  hind  legs,  though  long 
and  powerful,  are  not  saltatorial,  as,  indeed,  Is  evident  from  their  form 
and  position;  but  being  widely  separated,  and  capable  of  lateral  exten- 
sion, they  give  to  the  insect  a  grasping  power  which  is  very  great  in 
proportion  to  its  small  size.  The  curious  movements  in  which,  when 
about  to  alight  it  turns  itself  Itack  downwards,  and  seizes  the  leaf  with 
the  elongated  curved  hind  legs,  are  very  well  described  by  Zimmer- 
mann, in  the  passage  above  cited.

Raton  Mountain,  Colorado,  on  Rhus  (tromuticum.      The   bind    thighs 
are  rather  serrulate  than  toothed,  the    hind  Xxh'vx   arc  straight,   not  Hat- 
tened.     The  color  is  uniform  black,  the  elytral  striie  are  somewhat  con 
fused,  and  the  white  spot  is  very  small. 

3.  T.  tardipes,  n.  sp. 

Pale  brown,  head,  middle  of  prothorax,  body  beneath,  hind  legs  in  part, 
scutellum,  and  four  large  spots  on  the  elytra,  blackish.  Body  above 
thinly  clothed  with  long,  erect,  gray  hairs;  prothorax  not  densely  punc- 
tured, with  a  tuft  of  fine,  soft,  whitisli  hair  at  the  basal  angles.  Elytra 
with  rows  of  deep  subquadrate  punctures,  interspaces  narrow  convex; 
with  an  angulated  sutural  spot  in  front  of  the  middle,  of  soft,  white  hair, 
and  a  few  scattered  small  tufts  of  the  same;  each  elytron  with  a  large, 
dusky  spot  on  the  humerus,  and  a  smaller  round  one  near  the  tip.  Be-

rows  of  elytral  punctures  more  rcgidar,  and  the  white  spot  more  elon- 
gated. 

Tril)e  XVIII.      CEVTOKHYXC'HINI. 

This  numerous  tribe  C(msists  of  small  species  of  broad  f(;rm,  wit li  the 
beak  and  pector.il  groove  varying  according  to  genus.  They  are  distin 
gulshed  from  all  the  preceding  tribes  with  distant  front  coxa?,  bj'  the 
pygidium  being  perpendicularly  detlexed,  and  marked  with  a  deep  excava 
tion  (Mononychus),  or  with  a  continuation  of  the  acute  lateral  margin  of 
the  ventral  segments,  against  which  the  ai)ical  margin  of  the  elytra  rests. 
In  the  latter  case,  the  upper  part  of  the  dorsal  segment  is  finely  carinate; 
in  both  cases,  the  anal  segment  of  the  rj'  extends  in  front  of  the  excavation 
or  transverse  line.  In  all  the  genera  the  coriaceous  sutural  margin  of  the 
left  elytnm  is  much  wider  than  in  any  genera  of  the  C'ryptorhynchoid 
series,  including  Zygopini. 

The  antenna;  are  geniculate  as  usual,  inserted  about  the  middle  (jf  the 
beak;  the  funicle  is  6-7-jointed,  and  the  club  oval-pointed,  pubescent  and 
annulated.  The  side  pieces  of  the  me.sosiernum  are  usually  visible  from 
above. 

They  may  be  divided  into  four  groups,  the  first  of  which  indicates  more 
properly  a  sub-tribe. 

A.  Pygidium  without  transverse  line  for  reception  of  tip 

of  elytra;   pectoral  groove  extending  upon   the 

metasternum Monoiiycbi. 

B.  Pygidium  with  line  for  reception  of  tip  of  elytra, 

and  carinate  in  front  of  the  line; 
Pectoral  groove,  extending  behind  the  prosternum. .  t'cpiiodes. 

Pectoral  groove  anterior,  sometimes  effaced. 

Beak  long  and  slender C'cntorhynohl. 

Beak  stout,  usuallj'  short Phy tobii 

Group  I.     Mononychl. 

A  single  genus  constitutes  this  tribe.  The  species  are  of  l)road  form,  and 
larger  than  any  others  in  the  tribe,  and  are  easily  distinguished  b\'  tlic  pygid 
ium  not  being  carinate  in  front,  and  witli  no  transverse  line  for  the  reception 
of  the  tip  of  the  elytra;  the  declivous  exposed  portion  is,  however,  gibl)ous 
at  the  upper  part,  surrounded  with  an  impression,  distinctly  maigined  in 
the  male;  in  the  female  there  is  a  small,  very  deep  excav.ition,  surrounded

liy  a  thickened  margin.  The  eyes  are  partially  covered  when  the  head  is 
(k'tlexed,  and  the  beak,  which  is  long  and  cylindrical,  rests  in  a  deep 
groove  extending  through  the  pro-  and  mesosternum,  into  the  metaster- 
mim,  where  it  is  sharply  limited.  The  side  pieces  of  the  raeso-  and  meta- 
sternnm  arc  very  large.  The  ventral  sutures  are  curved  at  t he- 
sides;  the  first  segment  is  as  long  as  the  metasternum,  the  second  is  shorter, 
third  and  fourth  together  equal  to  the  second;  fifth  nearly  as  long  as  the 
first,  truncate  and  impressed  in  the  male.  Legs  slender,  thighs  slightly 
clubbed,  tibiae  obliquely  fringed  at  the  tip,  terminal  hook  very  small  at  the 
inner  angle.  Tarsi  with  the  third  joint  very  broad,  bilobed;  fourth  joint 
small,  with  a  single  claw. 

MONONYOHUS  Geriii. 

The  genus  is  sufficiently  defined  by  the  characters  of  the  group.  One 
species  occurs  in  our  fauna;  otherwise  it  is  represented  by  six  species  in 
Europe,  Northern  Asia,  and  one  in  the  Canary  Islands.

Canada  to  Georgia,  on  Iris.  Say  states  that  it  also  occurs  on  the  flowers 
of  Ceanothus  americanui,  and  Verbascum  thapsus  in  July. 

Group  II.     Coellodes. 

In  the  species  of  this  group  the  eyes  are  partially  covered  by  postocular 
lobes,  when  the  head  is  deflexed,  and  the  pectoral  groove  extends  into  or 
beyond  the  mesosternum,  the  l)eak  is  long  and  cylindrical.  The  side  pieces 
of  the  meso-  and  metasternum  are  large  and  wide.  The  ventral  sutures 
are  curved,  and  the  first  is  as  deeply  impressed  as  the  others;  the  second 
segment  is  shorter  than  the  first;  third  and  fourth  still  shorter,  fifth  nearly 
as  long  as  the  first.  The  pygidium  is  perpendicularly  deflexed,  marked 
with  an  elevated  angulated  line  for  the  reception  of  the  tips  of  the  elytra, 
in  front  f  which  it  is  carinated.  The  third  joint  of  the  tarsi  is  very  broad 
;ind  bilobed,  the  fourth  is  as  long  as  the  first,  with  two  claws,  which  are 
deft,  or  toothed.

addition,  tlic  pectoral  groove  prolonged  to  the  posterior  niaririn  of  the

seven  joints,  of  which  the  second  is  as  long  as  the  three  following.  The 
claws  are  armed  with  an  acute  tooth,  half  as  long  as  the  claw.

Middle,  Southern  and  Western  States.  Easily  known  hy  the  hroad 
form  and  dark  color;  the  prothorax  has  four  large  tubercles,  of  which  the 
outer  ones  are  acute;  the  dorsal  canal  is  prolonged  to  the  apical  margin. 
whicli  is  slightly  omarginated  thereby.  The  alternate  interspaces  of  the 
elytra  are  more  elevated  and  somewhat  uneven,  as  in  certain  Conotracheli. 
Length  2.7  mm.;  .11  inch. 

CNEMOQONUS  n.  g. 

The  tibia' of  one  species  are  so  different  from  those  of  the  other  Cixliodes. 
that  I  am  obliged  to  regard  it  as  a  separate  genus.  They  are,  namely, 
mucli  flattened  and  dilated  externally,  so  as  to  form  a  large  angle  near  the 
knee.  The  outer  apical  angle  of  the  front  tibia;  is  prolonged  in  a  toothed 
process,  as  in  Caliodes,  and  the  other  tibia;  are  obliquely  truncate  and 
fringed  externally.  In  other  respects  this  genus  agrees  with  Caliodes;  the 
pectoral  groove  is  not  prolonged  into  the  metasternum,  as  in  Craponius,  nor 
are  the  til)iie  grooved  externally  for  the  reception  of  the  tarsi.  The  thighs 
are  not  toothed,  and  the  claws  are  armed  with  a  short  tooth,  not  cleft,  as  in 
deUodes.

Widely  diffused  in  Europe,  from  Scandinavia  to  Austria.  I  have  a  spec 
imen  from  Great  Slave  Lake,  and  one  from  British  Columbia,  which  seem 
to  l)e  the  same.  Apart  from  the  generic  characters  above  given,  this  spe 
cies  is  easily  known  by  the  interspaces  of  the  elj'tra,  rough  with  small 
acute  tubercles  ;  near  the  base  there  is  a  small  cruciform  white  spot, 
formed  by  the  junction  of  a  short  sutural  line  with  a  transverse  one,  which 
<;xtends  to  the  third  stria.    Length  3.2  mm. ;  .125  inch. 

OCELIODES  Sch. 

In  this  genus  the  tibise  are  slender,  not  flattened  nor  toothed  on  the  outer 
margin,  but  the  front  pair,  in  some  si)ecies,  are  prolonged  at  the  outer 
apical  angle  into  a  short  process,  which  is  toothed  on  the  lower  edge.  The 
pectoral  groove  extends  as  far  as,  but  not  upon,  the  metasternum.  The 
claws  are  nearly  cleft,  the  inner  parts  being  almost  contiguous,  as  in  most 
tipccies  oi  Anthonomus.

Group  IIL     Ceutorhynclil. 

Tlie  species  of  this  group  are  small,  and  of  the  broad  ovate  form  usual 
in  the  tribe.  They  differ  from  the  preceding  group  by  the  pectoral  groove 
not  extending  behind  the  front  coxoe,  and  from  the  next  group  by  the  l)eak 
l)eing  long,  slender,  and  curved  ;  usually  about  lialf  the  length  of  the 
body.  The  eyes  are  small,  not  prominent,  and  are  partially  concealed  in 
repose  by  broad  prothoracic  lobes.  The  prosternum  is  suddenly  and  very 
deeply  emarginate  in  front,  and  the  antecoxal  ridges  defining  the  pectoral 
groove  are  acute  and  elevated  in  all  our  species. 

The  beak  is  stouter  and  more  coarsely  sculptured  in  (f,  and  the  last  ven- 
tral segment  is  impressed.*  The  species  in  our  fiiuna  are  not  very  numer- 
ous, and  all  belong  to  Ceutorhynchus ;  some  European  species  with  G- 
jointed  funicle  have  been  separated  under  the  name  Ceutorhynchidius, 
but  I  see  nothing  in  our  species  sufHcient  to  warrant  the  adoption  of  such 
a  division. 


*  By  an  unfortunate  error,  Suffrlnn  (p:nt.  Zeltung,  IS-l.j,  lO'i)  has  stated  that 
the  females  have  tlie  ventral  Impression.  Thompson,  however,  (Skand.  Col. 
vii,  passim),  reports  the  sexual  difference  correctly.

ceding  most  of  the  .scales  are  oval. 

Group  IV.     Phytobll. 

The  species  of  this  group  difler  from  the  Ceutorhynehi  only  by  the  beak 
being  stout,  and  usually  short,  in  one  instance  scarce!}'  as  long  as  the  pro- 
thorax.  The  prothoracic  lobes  are  feeble  or  wanting,  the  eyes  are  some- 
times partially  covered  in  repose,  sometimes  entirely  free.  The  pectoral 
groove  is  sometimes  well  defined  by  anteco.\al  ridges  on  the  prosternuni, 
but  occasionally  these  are  absent.  The  rirst  genus  exhibits  a  very  singvilar 
reversion  towards  the  Bayous  group,  Mith  ^  hich  it  might  indeed  be  placed, 
were  it  not  that  the  pygidium  is  exposed,  Uud  similar  in  sculpture  to  tlmt 
of  the  other  members  of  the  present  tribe,  and,  also,  that  other  characters 
correspond  with  the  position  here  assigned  to  it. 

The  genera  are  somewhat  diflicult  to  define,  in  consequence  of  the  im- 
portant structural  characters  by  wliich  the  species  are  distinguished.  It 
is  probable  that  they  will  be  increased  in  future,  by  those  whose  views 
tend  to  the  multiplication  of  genera,  but  for  the  present,  I  think  that  the 
divisions  liere  adopted  express  both  conveniently  and  naturally  the  aflini- 
ties  of  tlie  species  known  to  me.

In  this  genus  the  beak  is  stout,  cylindrical,  nearlj'  as  long  as  the  protho- 
rax  ;  the  eyes  are  small,  rounded,  convex  and  fully  exposed.  Prothorax 
not  much  wider  than  tlic  head,  wider  than  long,  slightly  narrower  at  the 
tip,  truncate  befon;  and  behind,  witli  a  small  angle  at  tlie  scutellum ;  tlie 
disc  is  feebly  longitudinally  impressed  behind  the  middle,  and  the  lateral 
tubercles  are  small  and  indistinct.  Elytra  deeply  striate,  nearly  twice  as 
wide  as  tlie  prothorax,  and  about  tliree  times  as  long,  voluminous,  broad 
at  tlic  base,  gradually  narrowed  behind.  Pygidium  triangular,  exposed. 
Legs  long,  slender,  tibiie  nearly  straight,  not  mucronate  ;  tarsi  not  dilated, 
last  joint  as  long  as  the  others  united,  with  ratlier  large  simple  claws. 

A  remarkable  and  easily  recognized  genus,  of  which  but  one  species  is 
known.  Schonherr  divided  P/t.y<(>i/«,')  into  two  groups  of  whicli  the  first 
{genuini),  was  characterized  by  long  slender  tarsi.  There  is,  tlierefore, 
no  excuse  for  retaining  the  name  for  tlie  second  group,  (sptirii)  and  it  must 
be  restored  to  this  genus  afterwards  named  Euhryrhinit  by  Tliom.son.

cited  ;  it  is  rare  in  northern  and  middle  Europe,  on  Potainageton  and  other 
plants,  below  the  surface  of  the  water.  It  is  a  small  black  insect,  clothed 
with  depressed  greenish  yellow  scales  ;  the  prothorax  has  two  broad  dark 
stripes  ;  the  elytra  are  more  thinly  clothed  with  scales,  except  the  sutural 
interspace,  which  is  densely  covered.  The  antenna'  and  legs  are  bright

The  species  of  this  genus  are  easily  distinguished  by  the  short  stout  beak, 
which  they  have  in  common  with  Rhinoncus  and  C<  dog  aster,  being  com- 
bined with  prosternum  somewhat  emarginate  in  front,  but  without  antc- 
coxal  ridges.  The  eyes  are  round,  convex,  without  orbital  ridges,  and 
are  completely  exposed  in  repose,  on  account  of  the  entire  absence  of  the 
postocular  lobes  of  the  prothorax.  The  claws  are  simple  and  moderately 
large.  The  funicle  is  G-jointed,  with  the  first  joint  longer  and  stouter  ;  the 
club  is  rather  large,  oval-pointed,  annuhited  and  acuminate.  There  are 
but  three  species  in  my  collection  :

CCELOG ASTER  Sch. 

This  genus  is  easily  distinguished  from  both  lihinoncus  and  Pelenoinuit 
by  the  eyes  being  inserted  under  distinct,  acute,  superciliary  ridges  or  or- 
Iiits,  and  being  jiartly  covered  in  repose.  There  are  also  important  ditt'er- 
<'nces  in  the  sternal  pieces;  the  prosternum  is  still  more  deeply  and  sud- 
denly eniarginate  in  front,  so  as  to  reach  almost  to  the  front  coxae,  which 
also  reach  almost  to  the  hind  margin,  and  are  more  widely  separated  than 
in  either  of  tlie  genera  just  named;  the  ridges  in  front  of  the  coxtc  limiting 
the  pectoral  groove,  are  much  stronger.  The  mesosternum  is  truncate  be- 
liind  at  the  middle,  and  enters  less  into  the  formation  of  the  middle  coxal 
cavities.  The  intercoxal  process  of  the  metasternum  is  therefore  almost 
square,  and  the  middle  coxse  are  more  posterior  than  in  the  other  genera. 

Tlie  beak  and  claws  vary  according  to  species;  the  funicle  is  6-joinle(.l, 
the  fii-st  joint  being  stouter,  and  the  others  slender  ;  second  and  third  elon- 
gate ;  4-()  sliorter,  equal,  scarcely  thicker,  club  elongate-oval,  pubescent, 
acute  at  tip. 

Three  species  are  known  to  me,  of  which  the  first  is  the  type  of  the 
genus. 

A.  Beak  slender,  claws  cleft  ;  eyes  nearly  covered  in  repose.

The  species  of  tliis  genus  have  the  broad  stout  form  usual  in  the  trihe, 
iuul  only  (litfer  from  PelenomuK  by  the  prostcrnum  being  deeply  emargi- 
nate  in  front,  with  distinct  anteeoxal  ridges. 

The  middle  ooxse  are  normal  in  position,  ^their  cavities  being  formed 
eqiially  by  the  meso-  and  metasternum,  whereby  it  diflfers  notably  from 
Ccelof/aster;  it  also  ditt'ers  from  that  genus  by  the  eyes,  which  are  rounded 
and  convex,  as  in  the  other  genera,  and  without  any  trace  of  superciliary 
ridge. 

Tlie  funicle  of  the  antenna;  is  7-jointed.  and  tlie  claws  cleft  are  in  our 
species.

casilj'  known  from  our  other  Ceutorhynchoids  by  the  larger  size  and  con- 
spicuous elongate  sutural  white  spot  at  the  base  of  the  elytra.  The  pro- 
thorax  is  very  coarsely  punctured,  feel)ly  channeled,  and  the  lateral  tuber- 
cles are  not  very  distinct.  Length  4  mm.;  .10  inch.  I  do  not  know  why

is  feebly  channeled,  and  the  lateral  tubercles  are  acute.  The  antenna-  and 
legs  are  fulvous  yellow.  The  elytra  are  marked  with  a  similar  elongate

Southern  and  Western  States;  Florida  to  Hlinois;  Gilroy,  California. 
Remarkable  for  its  elongate  form,  and  the  absence  of  i)rothoracic  tubercles. 
The  eyes  are  round,  and  barely  touch  the  prothorax  in  repose.  The  ante- 
eoxal ridges  are  very  strong,  but  the  prosternum  is  hardly  emarginate  in

An  imiwrtant  type  of  CurciMonidce,  containing  numerous  genera  and

iribo  thill  the  iii.artst  approach  to  Calandrida  and  ros»o« iWd;  is  nuuU',  in 
form  and  general  apijcarance,  though  the  I'ainily  characters  arc  (juitc  dif- 
ferent. 

The  following  characters  will  enable  them  to  be  distinguished  from  the 
other  tribes  iu  which  the  front  cox.e  are  separate. 

Beak  not  received  closelynipon  the  sternum,  which  however  is  some- 
times broadl}'  sulcatc  in  front  of  the  anterior  coxte;  when  this  groove  does 
not  exist,  there  are  sometimes  seen  {Mnilarm)  two  short  approximate 
ridges,  limited  inwards  by  an  impressed  line,  whicli  may  l)e  regarded  as 
the  last  remnant  of  the  pectoral  groove.  In  other  cases  (Baria  ittriutus) 
even  these  lines  disappear,  and  the  merest  trace  of  a  concavity  remains  in 
the  apical  constriction  of  the  i)rothorax,  which  in  all  the  species  is  not 
emarginatc  l)eneath,  and  is  destitute  of  postocular  lobes.  In  many  others 
even  this  slight  concavity  or  flattening  is  wanting,  and  the  apical  part  of 
the  prothorax  is  altogether  cylindriail,  al)ove  and  beneath.  The  meso- 
and  metasternum  are  closely  united,  and  the  suture  between  them  is  fre- 
quently obliterated.  The  side-pieces  of  the  nu'sothorax  are  so  extended 
outwards  and  upwards,  that  they  intervene  strongly  lietween  the  base  of 
the  prothorax  and  the  elytra  The  sides  of  the  latter,  therefore,  become 
obliquely  truncated,  giving  a  form  not  ()l)served  in  any  of  the  i)receding 
tril)es.  The  other  characters  are  soiuewhat  variable.  The  i)ygidium  is 
sometimes  exposed,  s  onetimes  covered.  Tlie  claws  are  sim])le,  and  either 
divergent,  connate,  or  even  (B<(  •ilepton)  single. 

The  genera  in  our  fauna  represent  two  groups: 

Pygidium  exjiosed,  usually  vertical;  fifth  ventral  segment 

in  the  latter  case  truncate  or  subemarginate Barldci*. 

Pygidium  oblique  or  horizt)nlai,  not  fully  exposed;  fifth 

ventral  segment  rounded  at  tip Centrlnl.

Group  I.     BarldeM. 

The  separation  between  this  group  and  the  Centrini  is  not  very  dcflnite, 
though  characters  such  as  the  perpendicular  pygidium,  and  the  shorter  and 
stouter  beak,  seen  in  most  of  the  species,  do  not  occur  in  the  last  named 
group.  The  main  character  to  be  relied  on,  in  the  absence  of  the  easily 
recognized  habitus,  is  that  the  elytra  are  more  broadlj-  separately  rouiuled 
at  tip,  and  the  i>ygidium  thus  becomes  more  exposed. 

Pygidium   oblique;   fifth    ventral    segment    longer, 

rounded  at  tip;  outer  joints  of  funiole  but  little 

broader,  club  large,  elongate-oval,  pubescent ....  2.

ORTHORIS  n.  g. 

This  genus  contains  a  sparsely  pubescent  species  from  California,  which 
lias  a  singular  resemblance  in  form  to  Orc?iesle.<<.  It  differs  from  the  other 
gencnv  of  this  subtribe  b}-  the  beak  l)eing  long,  slender,  cylindrical  and  not 
curved;  it  is  separated  from  the  front  by  a  transverse  impression,  as  usual. 
The  antenna-  are  inserted  about  two-fifths  from  the  end  of  the  beak,  the 
scai)e  does  n(>t  quite  reach  the  eyes:  the  first  joint  of  the  funicle  is  stouter 
and  longer  than  the  others,  which  are  nearly  equal;  the  club  is  elongate- 
oval,  as  long  as  the  joints  2-7  f  the  funicle,  and  entirely  i)ubescent  and 
sensitive.  The  front  coxte  are  nearly  contiguous  and  the  prosternum  is 
broadly,  though  not  deeply  sulcate  in  front.  The  legs  are  rather  long  aful 
slender,  tibite  not  mucronate  at  tip;  the  third  joint  of  the  tarsi  broad  and 
deeply  bilobcd:  claws  simple,  divergent.  The  prothorax  is  as  long  as  wide, 
gradually  narrowed  in  front,  with  sides  i>erfectly  straight.  Elytra  wider 
at  base  than  the  prothorax,  humeri  prominent,  sides  parallel,  tips  separately 
rounded,  pygidium  exposed,  obliquelj*  declivous;  fifth  ventral  longer  than 
the  preceding,  acutelj'  rounded  at  tip.

AULOBARIS  n.  g. 

I  have  separated  as  a  distinct  genus  some  specimens  from  the  Atlantic 
slope,  which  ditt'er  from  Burh  jjroper  by  the  more  slender  antennie;  the 
first  joint  is  scarcely  stouter  than  the  second,  and  the  latter  is  (juite  as  long 
as  the  first;  ihe  remaining  joints  C;{-7)  are  gradually  slightly  wider  and  the 
club  is  elongate-oval,  uniforndy  i)ubescent  except  at  the  base  of  the  first 
joint,  and  not  large.  The  beak  is  longer  than  the  [irothorax,  cylindrical, 
slightly  compressed  towards  the  base,  and  not  very  slender.  The  front 
coxa'  are  rather  widely  distant,  and  the  prosternum  is  deeply  and  broadly

As  I  liav(!  licre  restricted  this  genus,  it  contains  only  tliose  species  in 
whleli  the  club  of  the  nntennie  is  Rninll,  nearly  round,  with  the  fast  joint 
not  sensilive,  shininjr,  and  constituting  more  than  one-half  the  mass.  The 
claws  are  separate,  divergent,  and  of  moderate  size,  and  in  some  of  the  spe- 
cies {Hparm,  &c.)  small.  The  beak  is  stout,  usually  short,  and  nuifli  curved; 
the  frontal  constriction  rather  deep;  sometimes  it  is  a  little  longer  than 
the  prothorax.  The  fnmt  coxa-  are  never  very  widely  separated;  the  pro-

Middle  and  Southern  States.  I  have  retained  tliis  name  for  a  species 
which  is  quite  distinct  from  all  others  in  our  fauna.  The  well  marked 
structural  characters  which  enable  our  species  of  Bdris  to  be  easily  si'jja- 
rafed,  were,  however,  not  perceived  by  Say,  nor  by  the  collaborators  of 
Schonherr,  and  I  am  therefore  doubtful  if  the  jiresent  nani!;  should  lu'  prt- 
served.  As  far  as  I  can  judge  from  the  descrii)lions,  this  spec  es  is  the  one 
intended  by  Hoheman,  founded  upon  a  typical  si)ecimen  from  Florida  scmt 
by  Say,  and  on  others  from  Souih  America.  Hut  I  am  very  uncertain  if  it 
l)e  the  one  originally  described  by  Say,  and  ((uite  doubtful  if  that  original 
be  the  same  with  tlie  one  sub.sequently  referred  to  (Cure.  Vi),  of  which  it 
is  said  that  the  punctures  of  the  elytral  inerspaces  "have  a  transxerse 
rugulous  appearance."  In  the  original  dv'scripion  (J.  Ac.  iii,  Hit),  these 
same  punctures  arc  declared  to  l)c  orbicular. 

Head  sparsely  punc:ulate,  beak  finely  punc'ured,  frontal  constriction 
strong;  pro'horax  strongly  but  not  dciusely  pune  ured,  scarcely  wider  than

ONYOHOBARIS  n.  g. 

Under  this  name  T  would  gix)up  those  species  in  which  the  club  of  tlie 
antennic  is  n\ore  oval,  en'irely  sensitive  and  pubescent,  the  (list  joint  funn- 
ing less  than  one-half  the  mass;  the  sc^oond  joint  of  the  funide  not  longer 
than  the  third;  and  the  claws  divergent  and  larger  than  usual. 

In  other  r(>siK>ct8  this  genus  agrees  with  7?«/'w,  and  the  species  maybe 
classified  similarly,  though  the  front  co.Me  are  usually  much  more  widely 
separated  than  in  Bavia.

The  species  of  this  genus  have  the  second  joint  of  the  funicle  no  longer 
than  the  third,  and  the  club  not  larger,  oval,  with  the  first  joint  i)ul)escent 
and  sensitive,  and  constituting  less  than  one-half  the  mass;  the  claws  arc 
approximate  and  slightly  connate  at  base.  In  these  respects  they  agree 
with  Trichoburis,  but  ditier  by  the  front  coxie  being  very  widely  sepa- 
rated, and  by  the  absence  of  dense  scaly  or  hairy  vesliture,  though  there 
are  a  few  scattered  scales  on  the  elytra  of  each  species.  The  prosternum  is 
broadly  sulcate  in  front;  the  limits  of  the  groove  are  less  sharply  defined  as 
in  Aulohiiris.

This  species,  from  the  material  now  al  my  command  seems  scjiarable 

from  J',  nii/rina  only  by  its  narrower  form,  the  sides  of  the  prolhonix  nearly 
parallel  behind,  and  by  the  entire  absence  of  smooth  dorsal  line  of  the  pro- 
thorax.  Specimens  from  Texas'  which  are  clearly  referable  to  /'.  nir/rina, 
vary  in  the  last  mentioned  character,  the  dorsal  line  being  either  distinct  or 
obsolete,  so  that  onlj'  the  form  of  body  remains  to  dis;inguish  tluni  apart. 
Length  2.T-3.3  mm.;  .11-.13  inch.     Illinois  to  Kjinsas. 

In  one  specimen  a  few  scales  remain,  indicating  a  vestilure  similar  to  the

that  the  second  joint  of  the  funicle  is  longer  than  the  third  is  incorrect.

a  few  white  scales  are  visible  at  the  base  of  the  third  interspace,  wliieh  in- 
duce me  to  believe  that  in  well  jireserved  spi'cimens  they  are  scattered  as  in 
the  i)reeeding  species.  The  prosternum  is  broadly  and  strongly  suleate, 
and  sparsely  punctured,  but  the  edges  of  the  groove  are  less  sharply  d 'fined

AMPELOGLYPTER  n.  g. 

This  genus  contains  species  which  depredate  on  the  small  steins  of  grape 
vines  and  allied  plants,  producing  excrescences.  Two  of  them  are  readily 
distinguished  from  the  preceding  genera  by  the  smooth  and  shining  surface 
of  the  elytra,  the  interspaces  of  which  are  wide  and  not  ininctured;  the 
stri:e  are  fine,  the  posterior  callus  prominent,  and  the  surface  undulated  by 
broad  transverse  iiupressi  )ns.  lu  these  respects  tliey  resemble  Mddarus, 
but  diller  by  the  shorter  and  stouter  beak,  the  stouter  antennie,  and  the 
broadly  excavated  prosternum,  which  is  not  suddenly  declivous  between 
the  coxic.  The  front  thighs  are  not  toothed,  and  the  claws  are  connate  at 
base . 
The  form  is  also  quite  dift'orent  from  Madarus;  the  elytra  are  a  little 
0    wider  than  the  prothorax,  as  in  B<(m.

In  tliis  genus  the  upper  surface  is  very  smooth  and  shininfr,  and  tlic  siir

the  lirsl  joint  of  llie  funicle  as  loiii;  as  tiie  three  t'ollowing;  eluli  elonnate 
oval,  annulated,  entirely  puheseent.  The  prosternum  is  extriinely  wide 
and  giiiiious  lietween  the  coxa-;  declivous  in  front,  not  excavated,  liul  with 
two  \ery  short  impressions.  Front  tiiiiihs  armed  with  an  olduse  tooth, 
claws  approximate,  hut  not  connate  at  hase. 

The  precedinsj;  trenus  makes  a  t^radual  transition  from  Iliirinto  }fitiuti'u,it, 
and  the  arrangement  of  Lacordaire  l)y  wiiicli  the  jjenera  just  nameil  are 
separated  in  two  dilferent  sul)tril)e8  is  manifestly  unnatural.

Massachusetts  to  Alabama,  Texas,  and  Kansas.  The  northern  specimens 
are  entircdy  black;  those  from  the  South  ami  West  have  the  protliorax  red. 
Although  Moheman  di'scrihed  all  the  thijihs  as  toothed,  I  find  that  the  mid- 
dle and  hind  pairs  are  quite  unarmed.    The  tooth  of  the  front  pair  is  rather 

large,  but  obtuse. 

Group  II.     <'eiitriHl. 

The  only  characters  I  can  give  for  the  recognition  of  this  group,  as  dis- 
tinguished from  Jiarides,  are  :  the  elytra  conjointly  rounded  at  tip,  or 
nearly  so  ;  the  pygidium  thus  becomes  entirely  covered,  or  oidy  partly 
exposed,  and  is  nearly  horizontal,  oral  most  somewliat  oblique,  and  never 
vertical.  The  last  ventral  is  consequently  regularly  rounded  at  tiii,  never 
truncate  or  emarginatc.  In  addition  to  these  characters  the  ventral  surface 
of  the  abdomen  is  more  convex,  frequently  ascends  obli(|uely,  as  in  Zi^t/o- 
pini,  but  in  a  nnu'h  less  degree.  The  tibial  hooks  are  less  developed  than 
in  Ihin'i*  and  its  allies,  and  in  many  species  are  scarcely  apparent.  The 
beak  and  antenna'  are  generally  of  more  slemler  form  than  in  Jiitris,  but 
these  characters  are  not  without  exceptions,  as  will  he  seen  below.

distinct  and  well  dcfmed  s^eiiera,  there  remains  a  tolerably  numerous  maas, 
whicli,  although  not  entirely  homogeneous,  consists  of  species  liaving  in 
common  tlie  following  characters.  The  study  of  f«)reign  specic^s  may  per- 
mit at  a  future  time  a  farther  subdivision,  but  the  transition  between  the 
extreme  forms  seems  so  gradual,  that  1  am  unwilling,  wRh  my  present 
knowledge,  to  indicate  tlic  manner  in  which  tliis  may  be  etfected. 

The  beak  is  long  and  slender,  cylindrical,  and  usually  curved,  but  some- 
times nearly  stiaight;  th(>  antenual  groove  commence  about  the  middh?, 
descend  obliquely,  and  arc  wider,  deeper  and  couHuent  behind.  INIandi- 
blcs  small,  tiattened,  ])oiuted,  prominent,  and  without  teeth.  Antemitu 
rather  slender,  funifle  7  jointed,  joints  l-;5  varying  in  length,  'l-T  coual 
in  length,  not  passing  into  the  club,  which  is  oval,  somewhat  poiiufi'  pu- 
bescent and  annulatctl.  Prothorax  narrowed  and  nu)re  or  less  consiricled 
in  front,  without  poslocular  lobes;  pri)steru\un  long  in  front  oi"  ii.cc.Aa!, 
which  are  ratluuMvidely  .-('paraled;  not  cmMrginale  in  front,  impressed  or 
not,  according  to  species.  Elytra  sometimes  elongate  with  parallel  sides, 
though  usually  narrowed  from  the  huiMcri,  .so  as  togi\e  a  rliomboidal  form 
of  body;  posterior  callosity  feeble,  tilts  usually  conjointly  rounded,  somc- 
thnes  separately  rouiuled,  exp(<sing  in  the  latter  case  a  small  part  of  the 
pygidiuni,  which  is,  howe\cr,  horizontal,  and  not  vertical,  as  in  Burk  antl 
its  allies.  The  middle  and  hind  cox;e  an;  widely  s(.'i)arated;  metasternuui 
r^ither  short,  with  wide  episterna  in  the  rliomboidal  species;  h)nger,  with 
narrower  cpisleriia  in  the  elongate  sp-'-cics;  but  in  Ik.  li  cases  distinctly 
wider  before  and  behiiul.  ^'enlral  surface  ascending  in  some  si)e(;ic3, 
nearly  horizontal  in  otlieii.;.lirst  and  second  joints  long(,'r  tluui  tliirtl  and 
fourth  ;  tifth  sometimes  longer,  sometiuns  not  longer  than  IIk;  fourth  : 
first  suture  subsinuate,  the  others  strongly  augulated  at  the  sides. 
Thighs  unarmed,  tibia?  not  striate  on  the  outer  side,  very  feebly  mucronale 
at  till;  tarsi  with  the  third  joint  very  broad.  liilolK'd.  last  joint  long,  wi» 
stout,  divergent  claws. 

In  the  males  of  several  sitecies  the  prostcrnuui  just  in  front  of  the  coxte  is 
armed  with  a  slender  process,  which  varies  in  length  according  to  the  in- 
dividual, but  not  according  to  species. 

A.  Elytra  separately  strongly  rounded  at  tip:  pygidiuni  partly  exposed;

An  abundant  species  over  tiie  whole  of  the  Atlantic  district.  Varies 
consid:  rably  in  size  (8-4.7  mm.;  .12-.18  inch),  the  smallest  specimens 
occurring  in  all  parts  of  the  country;  also  in  form,  some  of  the  smaller 
siieciiiiens  from  Texas  being  less  robust,  with  the  sides  of  the  i)roth()rax 
less  rounded;  also  in  vestiture,  which  is. sometimes  denser  and  j'cllowish,  and 
sipiaiuosc  upon  the  elytra,  in  specimens  from  Texas.  The  white  scales  of 
the  scuieilum  are  not  vnifre(iuently  removed  by  abrasion.  Tlie  antennie 
are  stonier  than  in  the  following  species,  and  thesecond  joint  of  the  funicle 
of  the  aiitenme  is  distinctly  longer  than  the  third;  the  prosternum  is  deeply 
transversi'ly  impressed,  and  is  flattened  behind  tlie  impression,  but  has  no 
trace  of  spines  in  either  sex.  The  metasternal  episterna  are  wide;  the  fifth 
ventral  is  scarcely  longer  than  the  fourth.  The  anal  segment  is  exposed  in 
the  i\  and  is  slightly  declivous.  Of  all  tlie  species  in  our  fauna,  this 
makes  the  ne;  rest  approach  to  Baris.

any  demuled  spots.  Tlie  second  joini  of  tlie  funicle  is  as  long  as  tlu-  lirst, 
but  more  slender.  The  elytra  are  conjointly  rounded  at  tip,  and  the 
pygidium  is  not  visible.  The  prosterniim  is  transverselj'  impressed  and 
flattened,  as  in  the  preceding  species,  not  armed  in  the'tj^;  the  eniargina- 
tion  in  front  of  tlie  mesosternum  is  wide  and  deep,  limited  liy  sliarp 
angles.  The  metalhoracic  episterna  are  wide,  and  the  fifth  veniral  but 
little  longer  than  the  fourth.

14.  C.  decipiens,  n.  sp. 

More  elongite  than  the  preceding,  but  otherwise  closelj*  resembling  it. 
The  beaiv  is  similarly  curved  and  sculptured,  but  is  longer.  Tlie  ])rothorax 
is  not  constricted  in  front,  and  the  scales  are  somewhat  less  narrow,  though 
also  directetl  transversely;  the  sides  are  much  less  rounded,  'i'lie  elytra 
are  deeply  striate,  clothed  with  narrow,  pale  scales,  arranged  in  ra'lier  con- 
fused single  series  on  the  inner  interspaces,  but  with  regular  rows  on  the 
outer  ones.  Tiie  body  beneath  is  densely  clothed  with  oval  pale  scales; 
the  prosternum  is  transversely  impressed  as  usual,  but  also  slightly  foveate 
and  flattened,  though  the  fovea  is  concealed  by  the  scales.  The  front  coxae 
are  not  widely  separated,  the  metathoracic  side  pieces  are  wide,  and  the 
fifth  ventral  segment  is  nearly  as  long  as  the  third  and  fourth  united.  Fun-

Tribe  XX.     iioRtioPiKi. 

The  sub-family  of  genuine  Ciirrnlioniihv  fitly  closes  wilh  a  very  anoma- 
lous insect,  which  whih'  having  relations  with  several  of  the  curlier  tribes, 
exhibits  in  adtlilion  a  character  which  is  o:lu'r\vise  se(>n  in  one  of  the  sub- 
families of  the  Gahindridtr.  The  eyes,  namely,  are  very  large,  transverse, 
and  coarsely  granulaU'd;  they  are  widely  separated  above,  b-ui  nre  nearly 
contiguous  lieneaih.  It  follows  from  this  that  the  antennae  in  repose  must 
be  received  in  front  of  the  eyes,  which  therefore  form  as  it  were  a  collar  be- 
neath; and  the  antennal  grooves,  which  are  deep  and  obli(pie,  a'.taining  the 
ej'cs  near  the  upper  end,  are  suddenly  and  acutely  flexed  iieneath,  forming 
a  deep,  transverse  excavation  in  front  of  the  eyes. 

The  beak  is  shorter  than  the  prolhorax,  stout,  somewhat  flaMcneil,  a  little 
wider  a:  tip  than  base;  the  mandibles  arc  rather  flattened,  acme  at  tip, 
toothed  on  the  iuuer  side.     The  gular  peduncle  is  small  and  narrow,  ciar-

HORMOPS  n.  g. 

The  single  species  representing  this  genus  and  tribe  in  our  fauna,  is  a 
small,  incnnsi)icuous  black  insect,  thinly  clothed  with  rather  coarse  yellow 
hair,  and  reminds  one  in  general  ai>i)earance  of  the  Erirliine  genus  Prorat 
(p.  102).  The  characters  as  above  detailed  are  quite  anomalous,  and  no 
further  generic  description  is  at  jiresent  necessary.  It  is  possible  that  it 
may  have  relations  wi;h  some  of  tlu;  anomalous  genera  placed  by  Mr.  Wol- 
laslon  among  the  Coxnoiiiihr,  but  as  I  have  had  no  opporlunily  of  studying 
them  in  nature,  I  can  but  timidly  suggest  the  propriety  of  comparing  this 
genus  with  those  genera  of  Co.uonidif  in  which  the  eyes  are  dispo.ied  to  be- 
come confluent  beneath.  The  entire  facies  of  this  insect  is  so  purt'ly  Cur- 
culionideous  that  (tlie  se.vual  characters  being  unknown),  I  would  be  un- 
willing to  place  ii  in  any  other  family.

Subfamily   V.     BALANINIDJE. 

The  single  genus  which  constitutes  this  subfamily  has  been  lioretofore 
arranged  as  a  tribe,  in  the  vicinity  of  Anthonomini.  It  differs,  however,  from 
that  tribe,  as  from  all  other  Coleoptera,  known  to  n»e  by  the  movement  of  the 
mandibles  being  vertical  instead  of  horizontal;*  the  mandibles  are  short,  pyr- 
amidal and  acute,  and  the  condyle  ison  the  upper  side;  the  teeth  seen  in  mcst 
Curculionidtc  are  wanting;  the  inner  edge  is  mori'  convexly  curved  than  the 
outer,  so  that  in  the  ordinary  position,  the  jwints  seem  slightly  divergent.  In 
general  appearance,  as  well  as  by  the  extension  of  tlie  mesothoracic  epimera, 
so  as  to  give  an  oblique  outline  to  the  elytra  near  the  base,  this  subfamily 
seems  to  me  to  approach  Ce>Urinu»  more  than  Anthonomua  ;  the  risult  of 
this  obliquity  is  that  the  tenth  elytral  stria  commences  at  the  margin,  oppo- 
site the  anterior  end  of  the  me;ath</racic  episterna,  as  in  all  Burini. 

The  beak  attjiins  in  length  and  attenuation  the  greatest  development;  in 
the  (f  it  is  rarely  shorter  than  the  body;  in  the  9  it  is  frequently  twice 
the  length,  and  is  used  to  nmke  the  iwrforatiou  into  which  the  egg  is  sub- 
seciuently  introduced.  The  great  thickness  of  the  husks  of  the  fruits 
(chestnuts,  walnut,^,  hickory  nuts,  &c.),  depredated  on  by  these  insects, 
necessitates  a  very  long  perforating  instrument  to  reach  the  kernel,  upon 
Avhich  the  larva  feed?. 

The  mouth  organs  arc  small,  the  gular  peduncle  very  long  and  narrow. 
Tlie  antenniB  are  inserted  a  little  before  the  middle  (j^),  or  behind  the 
middle  (9)  of  the  beak,  and  are  very  long  and  slender;  the  funicle  is 
7-jointed;  the  first  joint  is  either  hmger  or  shorter  than  the  second,  and  the 
outer  joints  are  gradually  a  little  less  elongated;  club  elongate  oval,  pointed, 
annulated  and  pubescent.  Eyes  rather  large,  flat,  nearly  rounded,  finely 
granulated.  Prothorax  rather  long  in  front  of  the  coxir,  which  are  contig- 
uous; broadly  emarginato  in  front,  without  postocular  lobes;  pronotum 
rapidly  narrowed  in  front,  sides  rounded,  base  slightly  bisinuate.  Scutel- 
lum  distinct.  Elytra  narrowed  behind,  tips  separately  rounded,  pygidiunj 
more  or  less  exposed.  Side  jiii.'ces  of  nu'sothorax  attaining  widely  the  base 
of  the  prothorax,  and  truncating  the  humeral  outline  of  the  elytra;  meta- 
tlioracic  episterna  narrow,  dilated  in  front.  First  ventral  segment  longer 
than  the  second,  and  closely  united  with  it;  the  others  an  nearly  eipial  in 
length.  Middle  coxie  modi-rately  distant,  hind  coxa;  widely  distant,  not 
attaining  tlie  clylral  margin.  I^egs  long,  thighs  clavate  and  strongly 
toothed  in  our  species;  tibiae  slender;  truncate  at  tip,  not  mucronate  ; 
tarsi  dilated,  claws  divergent,  to<»tlu'd.

large,  rounded.  The  acute  (,'dge  of  tiie  ventral  segments  and  of  tlie  melu- 
thorax  is  iirominent  and  fits,  as  usual,  into  the  elytral  gro<jve. 

Legs  not  slender,  moderate  in  lengtli;  tliigiis  elavate,  front  tii)ia.'  sinuate, 
and  obliipiely  grooved  on  the  inner  sidi;  in  Bretithidiv,  and  armed  with  a 
hook  on  the  outer  tip,  and  a  spine  on  tlie  inner;  middle  and  iiiiid  tibia* 
truncate  at  tip,  with  two  small  fixed  si»iirs.  Iiv  Ciflitu  the  til)iie  mv  all 
slender,  straight  and  not  inucronate  at  tip.  Tarsi  spongy  pubescent  lie- 
neath,  with  the  third  joint  bilobed.  Claws  large,  simple  and  divergent, 
except  in  VyUt»,  where  the}'  are  small  and  connate  at  base. 

This  highly  specialized  family  is  the  last  of  those  in  which  the  male  is 
provided  with  an  ailditional  dorsal  segment.  The  mouth  organs  vary  to  a 
greater  degree  than  they  do  ill  Curculionidir,  though  usually  the  umntuni  is

developed  to  such  an  extent  as  to  conceal  the  ligula  and  labial  palpi.  Of  the 
genera  known  to  me  Vylas  is  the  only  one  in  which  the  niaxllUe  are  ex- 
posed l>y  the  nientum  not  filling  coinjjletely  the  buccal  cavity,  though  other 
cases  are  mentioned  by  Lacordaire. 

But  what  is  most  curious,  is  that  while  the  mandibles  of  the  9  preserve 
the  pineer-form  seen  in  many  Curciilionidie,  and  the  beak  is  slender,  and 
in  some  species  extremely  long,  for  the  purpose  of  performing  its  function 
as  an  accessory  organ  of  generation,*  in  the  rf  the  mandibles  assume  a  flat, 
curved,  and  pointed  form,  resembling  those  of  ordinary  Coleoptera.  This 
sexual  character  is  exhibited  even  in  those  genera  in  wliich  the  beak  of  the 
(^  is  nearly  as  slender,  and  the  moulh  as  small  as  in  the  9- 

Tiie  explanation  of  this  ditl'erence  in  the  mandibular  structure  is  afforded 
by  the  interesting  remarks  of  Mr.  A.  II.  Wallace,  concerning  the  wonder- 
ful i)ugnacity  of  the  (^  c?  when  in  proximity  to  the  9-  -^'i  excellent  ac- 
count of  the  assistance  given  by  the  (/*  to  the  9  when  siie  is  occupied  in 
boring  the  hole  in  which  the  egg  is  placed,  is  also  given  by  C.  V.  lliley,f 
from  observations  made  by  his  correspondent  W.  R.  Howard,  of  Forsyth, 
Missouri, 

These  coml)ats,  however,  result  in  no  injury  to  either  of  the  parties  en- 
gaged; the  dense  chitinous  covering  allbrds  a  perfect  protection;  the 
weaker  male,  overcome  by  exhaustion,  eventually  flees,  and  leaves  to  his 
more  vigorous  victor  the  honorable  task  of  guarding  and  assisting  the  fair 
object  of  strife  in  her  efforts  to  preserve  the  species. 

The  habits,  therefore,  of  these  insects,  as  well  as  their  peculiarities  of 
structure,  deserve  a  closer  attention  than  has  yet  been  given  totliem. 

The  smooth  eyes,  tiie  reticulations  of  which  are  seen  only  through  the 
transparent  integument,  and  the  form  of  the  front  tibiie,  indicate  a  resem- 
blance, though  a  remote  one,  to  lihyitHodidir.  such  as  might  perhaps  exist 
among  objects  of  quite  difterent  nature  originating  in  the  sau\e  period  of 
time.  The  geographical  distribution  of  the  Brenthidie  is  al.so  favorable  to 
the  idea  that  they  rei)resent  a  toleraljly  ancient  form  of  life. 

The  great  extension  of  the  longitudinal  axis  of  the  body  exceeds  in  some 
members  of  this  family  any  proportion  that  occurs  in  other  Coleoptera;  and 
it  is  singular  to  see  that  a  character,  which  usually  indicates  feebleness  of 
development,  is  here  associated  witli  densely  chitinized  integuments,  and 
great  complication  of  donu^slic  life. 

The  family  divides  itself  naturally  into  two  subfamilies,  the  characters 
of  which  have  been  sufHciently  exposed  above.

Subfamily    I.       BRENTHID^:    (genuini). 

Of  this  family  two  genera  belong  in  the  faunal  limits  treated  of  in  this 
memoir,  though  one  of  them  {Tirenthuii),  is  in  a  political  sense  extra  limitul. 
having  occurred  in  Lower  California. 

Tliese  two  genera  represent  in  the  arrangement  of  Lacordaire  separate 
groups,  but  in  the  plan  of  subordination  of  characters  herein  adopted,  they 
seem  to  indicate  what  I  have  called  tribes,  which  may  be  dislinguisluHl  by 
the  sexual  and  other  ditterences  in  the  head,  as  well  as  by  the  form  of  the 
prothorax. 

Beak  very  dissimilar  in  the  two  sexes;  antennie  not  very  remote  from 
the  eyes,  rather  slender,  not  compressed,  nor  clavate;  prothorax  convex, 
not  grooved AKRUE3iOUlxl.

Tribe  I.     ARKHK!«o»lxl. 


The  genus  Eupsali'»,  represented  in  our  fauna  by  a  single  species,  differs 
from  ArrJienodes  by  the  brilliant  lustre  of  the  surface,  and  by  the  bind  part 
of  the  head  being  less  prominent;  in  view  of  the  magnitude  of  the  varia- 
tions in  the  rf  (f,  which  I  have  mentioned  below,  I  have  great  doubt  of 
the  generic  value  of  these  characters;  neverlheless,  my  opinion  can  only 
be  tested  by  a  careful  study  of  foreign  species,  which  would  interrupt  the 
progress  of  the  present  memoir,  and  is,  moreover,  not  essential  for  the  elu- 
cidation of  our  own  fauna. 

The  distribution  of  Eupsalis,  even  as  thus  limited,  is  remarkable;  one 
species  in  North  America,  one  species  in  Guinea,  and  one  in  Madagascar, 
and  perhaps  one  in  Brazil.  It  is  worthy  of  remark  in  this  connt-ction,  that 
the  genus  Amorphoeephalus,  the  only  Brenthide  found  in  Europe,  is  also 
represented  in  Australia.*

black,  tlie  red  iind  llie  post  oaks  are  mtintioncd  us  those  which  are  known 
to  Ite  attacked.  By  some  curious  inadvertence,  Olivier  in  the  Encyclopedio 
Metiiodiiiue  cites  for  this  species  No.  84,  plate  ii,  f.  i);  a  totally  distinct  spe- 
cies, which  in  the  text  (v,  4ii!))  is  named  Ii.  m  litarU. 

A  description  of  this  very  well  known  insect  is  here  unnecessary,  hut  a 
notice  of  the  variations  wiiich  I  have  observed  in  the  head  of  the  males 
may  be  of  inlc^rest. 

The  females  vary  In  length  from  6.5  to  14  mm.;  .2.'i  to  .50  inch.,  from 
the  eyes  to  the  tip  of  the  elytra.  The  head  is  rather  8'ron;>;ly  constricted 
immediately  behind  the  eyes,  which  are  convex  and  prominent.  Imme- 
diately in  front  of  each  eye  is  a  deep  fovea;  and  in  advance  of  them  is  a 
deep  frontal  excavation;  the  ridges  above  the  insertion  of  the  antenna'  are 
prominent,  and  not  angulated;  the  beak  in  front  of  the  an'ennie  is  as  hmg 
as  the  joints  1-9  of  the  antennie,  which  are  shorterand  stouter  than  in  the  -^. 

The  males  vary  in  length  from  7.2  to  17  mm.;  .28-.G7  inch,  from  the 
eyes  to  the  tip  of  the  elytra.  The  head  affects  three  ditt'ereut  forms,  which 
seem  to  be  independent  of  size  : 

1.  The  head  is  suddenly,  but  not  strongly  constricted  behind  the  eyes, 
with  the  lateral  angles  obtuse,  but  distinctly  outlined;  the  ridges  above  the 
antennic  are  very  prominent,  angulated  behind,  and  separated  from  the 
front  by  a  deep  impression;  the  frontal  impression  is  large  and  deep,  and 
the  median  elevation  in  it  is  feeble;  the  beak  in  front  of  the  antenme  is 
strongly  dilated,  much  wider  than  long,  wiih  scattered  elevated  granules, 
and  with  a  well  developed  ridge  each  side,  which  is  suddenly  more  elevated 
at  its  posterior  end;  there  are  also  two  shallow  impressions.  The  mandi- 
bles are  as  long  as  the  beak  in  front  of  the  antennte;  the  cusp  on  the  inner 
side  is  distinct  and  the  apex  of  the  right  mandible  has  three  cusps,  that  of 
the  right  but  two.     This  form  occurs  in  Michigan  and  Georgia. 

2.  The  beak  in  front  of  the  antennae  is  not  transverse,  but  fully  as  wide 
as  long;  the  other  characters  as  in  (1).  This  form  occurs  in  Kansas  and 
Texas. 

3.  The  beak  in  front  of  the  antenna;  is  nearly  twice  as  long  as  wide,  the 
lateral  ridges  less  developed,  the  granulations  more  numerous,  the  mandi- 
bles comparatively  shorter  and  stouter;  the  frontal  impression  more  elon- 
gated, with  the  median  elevation  more  distinct;  the  ridges  above  the  inser- 
tion of  the  antenna;  are  less  prominent,  not  angulated  behind,  and  the  head 
is  less  suddenly  constricted  behind  the  eyes,  with  the  angles  so  much 
rounded  as  to  be  nearly  effaced. 

These  characters  are  somewhat  similar,  as  regards  the  development  of 
the  supra-antcnnal  ridges  to  those  observed  in  Lucanidce,  but  in  the  varia- 
tion of  the  length  of  the  beak  are  rather  anomalous.  They  indic^Ue,  how- 
ever, the  propriety  of  recasting  the  classification  of  this  family,  and  defining 
the  genera  and  species  by  the  invariable  characters  of  the  female,  rather 
than  by  the  perhaps  individual  modifications  of  the  male. 

The  measurements  given  above  show  a  slight  average  superiority  of  size 
in  the  male,  but  not  sufflcient  to  warrant  any  generalization  in  favor  of

sexutil  selection,  produced  by  tlie  bloodless  coinlmts  of  faese  insects;  wbicli 
seem,  so  fiir  as  the  records  go,  to  be  uctunted  nitber  by  ciiivulric  sentiment, 
than  by  animal  passion. 

Tribe  II.     brenthiki. 

Two  species  of  Brenthu*  collected  by  Mr.  Xantus,  at  Caprf  Sm  Lucas, 
Lower  California,  which  are  closely  allied  to  Mexican  species,  have  been 
fully  descril)ed  by  Dr.  Horn.*  I  observe  in  the  males  also  jjn-at  variation 
in  the  form  of  the  head  in  difTcrent  indlviduils,  althouijb  the  b'ak,  though 
shorter,  is  as  slender  in  the  cT  'is  in  the  9.  iml  the  mandibles  are  ecpialiy 
small,  but  different  in  form;  the  distance  from  the  eyes  to  the  insertiim  of 
the  antenme  is  projwrtionally  lon>!;er  in  tlie  larger  males. 

Tlie  head  is  deeply  excavated  beneath,  just  in  front  of  the  neck,  in 
B.  petit riKular in,  while  it  is  only  slightly  so  in  B.  hiciinnx.  In  B.  mexl- 
canus  there  is  a  short  but  deep  groove  in  the  same  jiosition.  Tlie  front 
femora  alone  are  toothed  in  B.  me.ticanus  and  lucanus,  while  they  are  all 
toothed  in  peninsularis. 


Subfamily    11.      CYLADTDiE. 

This  sub-family  represents  the  tribe  GyladeK,  of  Lacordaire,  placed  by 
liim  between  Eurhynchnu  and  Apioii,  and  consists  of  but  two  geui'ra,  one 
of  which,  Gylan,  occurs  in  Asia  and  Africa,  while  the  other,  Myrmecacelu*, 
is  found  in  Australia.  I  have  sufficiently  exposed  the  characters  of  this 
subfamily  in  the  description  of  the  family,  and  the  singular  f  >nn  of  the 
antenntc,  as  well  as  the  very  peculiar  appearance  of  the  ins.'ct,  Wk  enable 
it  to  be  easily  recognized. 

The  relations  of  these  insects  with  Brenthidce  were  well  recognized  by 
Fabricius,  Latreille  and  Olivier,  and  I  know  not  for  what  reason  they  liave 
been  lost  sight  of  by  more  recent  observtirs.

Family  YIII.     CALANDRID^. 

Mouth  cavity  variable  according  to  subfamily,  as  follows: 

1.  Gular  peduncle  very  long,  concealing  the  mentum  and  ligula,  buccal 
fissures  narrow  and  long;  mandibles  comj)resscd,  wi;h  three  apiail  teeth 
in  Gala  ml  r  Ida;  (.(jenmni). 

2.  FUK>r  of  the  mouth  so  prolonged  that  all  of  the  organs  are  concealed, 
e.vcept  the  mandibles,  which  are  coave.xon  the  inner  face,  with  three  apical 
teeth,  and  usually  diverge  externally  in  lihinidiv. 

3.  Gular  peduncle  rather  broad,  mentum  trapezoidal,  tmnsverse;  maxil- 
lary palpi  rather  large;  mandibles  flattened,  curved,  with  the  apex  acute, 
and  one  prominent  tooth  on  the  inner  edge,  in  Cossonidm. 

Antenna'  geniculate.  Inserted  near  the  base  of  the  beak  {Calandridm), 
or  about  the  middle  iRhinidcp  and  CoHnonidce);  scape  long,  funicle  vary- 
ing from  four  to  seven  joints;  club  variable,  with  the  basal  part,  and  some- 
times nearly  the  whole  surface  shining,  not  sensitive:  oval  and  annulated  as 
usual  in  Consonidie. 

Head  iK)rrected,  beak  at  most  capable  of  being  deflexed  vertically,  never 
narrowed  behind  the  eyes;  beak  sometimes  long,  sometimes  short;  eyes 
sometimes  small,  sometimes  very  large  and  transvers:-,  contiguous  beneath 
{1thi)iid(e\;  antennal  grooves  very  short,  and  not  receiving  the  scape  in 
Calandridte,  sudd(  v  deflexed  under  the  eyes,  and  receiving  the  scape  iu 
CoHHonidw. 

Prothorax  truncate  in  front,  not  emarginate  beneath,  prosternum  long  in 
front  of  the  coxie,  which  are  separated;  prosternal  sutures  effiired;  the 
transverse  suture  between  the  coxte  is  wanting  in  Calandridce  and  Cosso- 
nidie,  but  distinct  in  RhinidiP. 

Mesosternum  triangular,  truncate  behind,  side  pieces  varying  according 
to  genus  and  tribe;  middle  coxa^  separated,  cavities  rounded. 

Metasternum  usually  long,  episterna  varying  in  breadth,  broader  in 
front,  epiniera  large  in  some  Calandridm,  small  in  other  genera  and  sub- 
families; hind  coxa;  transverse,  oval,  not  attaining  the  side  of  the  abdo-

suture  is  cfTuced  at  the  middle;  the  third  and  fourth  sejrments  are  short,  and 
the  sutures  straight  and  deeply  impressed;  the  fifth  is  about  as  long  as  the 
third  and  fourtli  united,  and  is  rounded  behind.  The  dorsal  segments  are 
membranous,  (xcept  the  last,  or  pygidium,  which  is  large,  nearly  perpen- 
dicular in  Valandrida,  oblicpiely  iletlexed  in  the  other  subfamilies;  the

pygidium  as  in  Vareulioiiida  and  nreiUhidie;lh(i  lateral  edge  of  the  nie:a- 
thorax  and  of  the  ventral  segments  is  sharp  and  fits  into  the  lateral  groove 
of  the  i  iner  surface  of  the  elytra;  in  the  ('dsmnidd'  this  edge  continues  on 
and  around  the  last  ventral,  thereby  showing  a  tendency  towards  the  modi- 
fication finally  perfected  in  tlie  Scolytidix,  and  of  which  we  have  already 
seen  trac  's  in  the  lirenthidiv. 

Legs  UKxlerate,  varying  thougli  not  greatly,  according  to  genus;  thighs 
usually  stoutly  davate,  not  toothed;  tibiie  rather  short,  strongly  unguicu- 
late  at  the  outer  angle.  Tarsi  frequently  narrow  and  not  brush  like  be-

and  not  emarginate,  (certain  Sphenophori);  claws  divergent,  8imi)le. 

I  liave  embraced  in  this  family  several  very  distinct  forms  which  agree 
with  Vurculionida  in  general  characters,  but  difler  in  having  the  genital 
segment  of  the  c?  not  articulated  directly  at  the  end  of  tlie  last  dorsal,  but 
either  retractile  or  concealed  under  it.  While  the  mouth  organs  of  the  Co»- 
sonidit  are  similar  to  tliose  of  ordinary  CureuUonidiP,  and  submit  to  modi- 
fications similar  to  those  of  Ilylobiim  for  instance,  in  the  other  subfamilies 
there  are  specializations  which  do  not  otherwise  occur  among  Khynchophora. 

With  regard  to  the  affinities  of  the  membei-s  of  this  family,  it  may  be  said, 
in  general  terms,  that  the  Cdlandridce  show  an  alliance  with  the  Barini; 
the  lihinidce  continue  the  specialization  still  farther,  and  have  not  a  direct 
resemblance  to  any  other  tribe.  The  Consonidw  seem  to  be  a  connecting 
line  from  Ilylobiini  to  Scolytidce,  to  whicli  they  approach  very  closely  in 
Rhyncoluit. 

Three  subfamilies  occur  in  our  fauna,  the  characters  of  which  have  l)een 
sufficiently  indicated  above:  the  following  table  will  enable  them  to  be 
readily  distinguished.

Tribe  I.     KiiYKC'ifOPiioKiM. 

The  species  of  this  tribe  are  of  lars^e  size,  and  with  the  exception  of  Rhyn- 
cJiophontx,  iiave  the  mandibles  turned  outwards  as  in  the  Rhiiiidiv;  in  the 
genus  just  mentioned,  the  mandibles  are  of  the  usual  pincer-form  with  three 
small  ai)ical  teeth.  The  funicle  of  the  antennie  consists  of  six  perfoliate 
joints,  strongly  constricled  at  the  outer  end;  the  club  is  transverse,  trape- 
zoidal, corneous,  with  the  terminal  face  flat,  spongy  and  sensitive. 

One  species,  11  cruentatuit,  represents  this  sjiecies  in  the  Southern  States. 
It  is  jtarasitic  on  C'hamaropK  pitlmetto.  In  consequence  of  the  extension  of 
the  mesothoracic  epimera  upwards,  the  humenil  portion  of  the  elytra  is 
truncated,  as  in  Barini.  The  third  joint  of  the  tarsi  is  but  little  wider  than 
the  second,  not  emarginate,  fringed  at  the  apical  margin  beneath.  In  the 
(^  the  tibia",  and  to  a  less  extent  the  thighs  are  densely  fringed  with  long 
yellow  hair  on  the  inner  side:  in  the  9  ••>«  hairs  are  much  less  dense.  The 
genital  segment  is  sometimes  protruded;  it  is  nearly  smooth,  and  finely 
channeled  above  in  both  st'xes,  but  is  longer  and  narrower  in  the  9,  in 
which  sex  also  the  pygidium  is  more  flattened,  and  more  obliquely  narrowed 
at  the  tip . 

Tribe  II.     NPIIEWOPHORIXI. 

The  species  of  this  tribe  are  rarely  large,  but  never  very  sraiill.  The 
mandibles  are  always  pincershaped,  with  three  apical  teeth.  The  meso- 
thoracic epimera  are  large,  and  truncate  at  the  outer  side,  so  tl  t  tlie  out- 
line of  the  elytra  near  the  base  is  straight,  and  not  Mi(|'  :i8  in  ilic  preced- 
ing tribe;  the  metathoracic  episterna  are  rath 
small,  though  quite  obvious.

lateral  punctures  elevated.  S.  interxtitidlin  of  Cuba,  lias  the  same  punctu- 
ation of  prothora.v,  but  a  little  Htronj^er,  imd  the  apical  constriction  is  less 
marked;  the  lustn;  is  more  dull.  S.  roha»tior  Horn,  froni  Texas,  has  the 
form  of  prothorax  of  acupunctatus,  but  the  punclures  are  coarser,  and  the 
lateral  ones  are  less  elevated;  the  lustre  is  also  dull  as  in  S.  interittUiali*. 

2.  S.  yucoee  Horn,  fnmi  Csdifornia,  is  cpiitc  distinct  by  the  more  de- 
pressed upper  surface,  and  the  single  rows  of  punctures  on  the  interspaces 
of  the  elytra.

SPHENOPHORUS  Sch. 

The  species  S.  \^punctatHn  and  validu*  contained  in  Horn's  Group  ii, 
should  each  constitute  a  distinct  genus;  the  other  species,  in  which  the 
third  Joint  of  the  tarsi  is  not  spongy  beneath,  but  merely  pilose,  sometimes 
broad,  sometimes  narrow,  might  be  regarded  as  constituting  but  one  genus. 

OACTOPHAG-US    n.  g. 

I  would  separate  as  a  distinct  genus  a  species  of  large  size,  and  dull  vel- 
vety black  color,  which  differs  from  Sphennphoru»,  by  the  absence  of  in- 
equalities or  coarse  sculpture,  and  by  the  third  joint  of  the  tarsi  being  some- 
what tnvnsverse,  and  uniformly  densely  spongy  beneath;  the  first  and  sec- 
ond Joints  are  narrow,  and  glabrous  beneath.  The  tibiie  are  slender,  not  sin- 
uate, and  the  outer  part  of  the  tip  is  regularly  rounded,  not  at  all  truncate, 
or  angulated.  The  gular  peduncle,  though  deeply  channeled,  is  regularly 
rounded  at  the  end,  not  abruptly  subtruncate  as  in  Sphenophorun;  whereby- 
the  beak  remains  cylindrical,  and  is  not  at  all  compressed  at  tip.

above  the  insertion  of  the  anteiinie  are  much  stronger,  and  the  scape  of  the

Tribe  IIL     CALAXDREXI. 

This  tribe  consists  of  small  species,  in  which  the  mandibles  are  i)incer- 
shaped,  and  not  everted;  the  club  of  the  antennie  not  compressed,  and  the 
mesotlioracic  epimera  transverec,  acute  at  the  outer  end,  and  intervening 
between  the  luimeral  part  of  the  elytra  and  the  base  of  the  prothorax.  The 
anterior  part  of  the  last  dorsal  segment  of  the  abdomen  is  channeled  for  the 
reception  of  the  suturai  edge  of  the  elytra,  almost  as  in  AnthribtdtP.  This 
is  a  very  peculiar  character,  and  I  find  no  tracj  of  it  in  tlie  other  genera  in 
our  fauna. 

CALANDRA  Clauv. 

This  genus  differs  from  the  others  contained  in  the  tribe,  but  not  repre- 
si-nted  in  our  fauna,  by  the  anfennal  club  '.•■eing  oval,  tlie  corneous  part  sep- 
arated from  the  sensitive  [wvrt  by  a  transverse  line;  the  sensitive  part  being 
convex,  and  somewhat  pointed.  The  body  is  narrow,  and  elongate,  (juite 
different  to  that  observed  in  the  genera  of  the  two  preceding  tribes,  rather 
resembling  Itfuna  in  miniature. 

Three  species  occur  in  our  fauna;  they  have  been  distributed  in  the  ce- 
real grains  upon  wliich  they  depredate,  so  that  tlieir  original  h-.bitat  cannot

they  have  not  yet  become  naturalized.

Founil  in  every  part  of  the  globe;  universally  distributed  by  commerce, 
and  said  to  have  been  originally  derived  trom  Asia;  it  atfects  rice,  wheat, 
and  Indian  corn  (maize).  The  surface  is  dull,  and  the  jirothorax  densely 
punctured;  the  elytra  are  usually  ornamented  wit li  four  red  8iK>ts,  but  are 
sometimes  red,  witli  the  suture,  side  margin  and  tip  darker.

Subfamily   IL     lUIINID^li:. 

This  siii)(amily  corresi)onds  nearly  if  not  exactly  with  Laeordaire's  tribe 
iSipitfnfi's,  and  the  essi-ntial  ditferenccs  between  it  and  tiie  CdliuKlridti'  are 
in  the  position  of  the  buccal  opening  which  is  entirely  tit  the  end  of  the 
beak,  not  extending  upon  the  under  surface;  tlie  pygidium  is  not  large  and 
pcrpeiulieitlarly  declivous  as  in  the  last  subfamily,  but  Ci)vered  by  the  ely- 
tra, which  are  conjointly  rounded  at  tip;  anotlier  cliaracter  also  separates 
it  from  Calnndrida  (though  not  from  Laeordaire's  tribes  8lromho»eeride», 
and  OryrhynchidcK,  which  arc  not  icpresenied  in  our  fauna,  and  are  un- 
known to  me  in  nature);  tlie  eyes  are  strongly  granulated,  very  large,  a'ld 
confluent  on  the  under  surface  of  the  head. 

In  nearly  all  the  genera  mentioned  by  Lacrordaire,  tht;  mandibles  are  con- 
vex on  the  inner  face,  and  liie  apical  teeth  are  everted,  though  tliis  is  pro- 
babl}'  a  group  or  generic  charaet'.r  as  in  c(Mtain  tribes  of  CdUnulridtv.  The 
club  of  the  antennie  varies  in  form  accordini!:  to  genus,  and  is  not  annulated. 
The  tarsi  also  vary,  the  third  joint  being  narrow  in  some  genera,  wide  and 
bilobed  in  others.

rated from  it  liy  angulated  lines,  so  as  to  extend  farther  upon  the  sides  than 
upon  the  faces  of  the  club,  which  is  slightly  compressed. 

Proi  borax  longer  than  wide,  rounded  on  tlie  sides,  a  little  narrower  at  tip 
than  at  'a.se,  and  constricted;  truncate  before  and  behind.  Scutellum  small,

punctured;  c  mjointly  rounded  at  tip,  i)ygidium  s'.iglitly  prominent.  Legs 
slender,  thighs  not  clavate,  (ibiaj  mibsiniiate  on  tlie  inner  side,  and  feebly

species,  that  it  might  indicate  a  distinct  genus;  but  my  knowledge  of  Jihi^n- 
chophiira  at  that  time  was  not  sufficient  to  enable  me  to  pr()|»erly  define  it. 

Subfamily   III.     fOSSONIDyE. 

The  abnonnal  form  of  mouth  seen  in  the  two  preceding  subfamilies  is 
here  replaced  by  the  ordinary  buccal  cavity  and  mouth  organs  si'en  in 
Curcidiiniiilir.  The  gular  peduncle  is  rather  broad,  not  very  long,  the 
mentntn  and  lignla  witli  its  paljii  are  distinct,  and  modcratc^ly  large,  and 
the  ma\illa'  and  palpi  are  well  deveioiicd.  The  beak  varies  greatly,  being 
somelimi's  rather  long,  and  moderately  slender,  sometimes  so  short  and 
stout  as  to  become  indistinct.  The  antenna'  are  inserted  at  a  variable  dis- 
tance, being  sometimes  basal,  some;iines  nearly  ai)ical;  tlie  scape  generally 
extends  licyond  the  eyes;  the  funiele  has  from  four  to  seven  join  s;  the  club 
is  small,  oval,  partly  corneous  in  some  genera,  and  but  feebly  annidatcd. 
The  front  coxa'  are  sometimes  widely  se|  araled,  .some'imes  almost  contigu- 
ous. The  thighs  are  unarmed,  and  the  tibia'  are  aimed  in  our  genera  witli 
a  long  curved  spine  at  the  inner  apical  angle;  the  tarsi  are  varialile,  the 
third  joint  is  nsnally  not  broader;  in  oic  genus,  Dryophthoriis,  by  an  ex- 
ception ollierw  isc  unknown  in  the  family,  and  repeated  again  only  in  I'laty- 
pus  and  s>iine  other  genera  among  the  Scolytidie,  the  tarsi  arc  distinctly 
5-jointed. 

Neglecting  the  number  of  joints  in  the  ftuiide  of  the  antennie  as  being 
ratlier  of  generic  than  tribal  value,  1  would  divide  the  few  genera  repre- 
sented in  our  fauna  as  follows:

in  form  Calandra,  rather  than  any  genus  of  CoMonidie  known  to  me.  The 
antennal  c'ub  is  rounded,  oval,  corneous,  except  the  lip,  which  is  spongy 
and  not  annulated;  the  joints  of  the  funicle  are  only  four,  while  those  of  I  ho 
tarsi  aie  distinctly  live,  though  in  the  South  European  Cliivrorhinux,  ac- 
cording to  description,  tliis  anomaly  disappears,  and  the  tarsi  aie  4  jointed. 
The  metasternum  is  long  and  the  side  pieces  are  narrow;  the  tiist,  second 
and  rtflh  ventral  segnn  iits  are  very  large;  third  and  fourth  excessively 
short,  shorter  in  fact  than  in  any  other  genus  I  have  examined.  The 
antenna'  are  inserted  very  near  tiie  eyes,  which  are  coarsely  granulated  and 
transverse.

genus  would  probably  go  near  LymanteK,  which  is  Ihus  tiir  unknown  to  us, 
and  may  perhaps  liave  some  relation  to  the  European  Styphloderes. 

BesiilLs  the  luoie  slender  beali,  and  the  crusty  covering,  these  insects  dif- 
fcr  from  lliose  of  tlie  following  two  tribes  by  tlie  head  being  rather  peculiarly 
CDnstiictcd  behind  the  eyes,  which  arc  small,  rounded  and  very  coarsely 
granulated;  the  result  of  this  form  of  head  is  that  the  eyes  are  situated  on 
tlie  beak,  instead  of  at  the  sides  of  the  cranium  i)roper.  The  scutellum  is 
not  visil)Ie  in  eillier  of  our  genera,  and  I  am  inclined  to  believe  that  this 
will  be  found  a  cliaracter  of  the  group,  permitting  the  association  of  forms 
now  widely  separated.

singular  insect,  of  which  I  hope  more  specimens  may  be  obtained  than  the 
single  one  I  have  examined. 

Tribe  II.     COSSOSflXI. 

I  would  associate  as  a  distinct  tribe  certain  other  genem,  wliich  have  not 
the  body  covered  with  a  crust,  l)ut  siiining  and  bare;  .some  of  the  foreign 
geneni  are  more  or  less  seto.sc,  but  ours  are  glabrous. 

The  beak  is  never  very  short,  and  is  freciuently  dilated  at  tip;  the  anten- 
nic  are  inserted  near  the  tip,  or  at  the  middle;  the  antennal  grooves  fre- 
quently descend  rapidly  on  the  sides  of  the  beak,  and  sometimes  are  di- 
rected towards  the  eyes,  but  the  antennje  are  not  received  in  reiKise  in  a 
deep  transverse  gular  irroove  as  in  the  next  tribe.  The  club  varies  in  form, 
and  in  our  genera  the  funicle  is  7-jointed;  whether  any  of  tiie  genera  ol 
other  countries,  with  less  number  of  joints  in  the  fuiucle,  Iwlong  to  the 
tribe  is  here  constituted,  must  be  determintd  by  subscfpient  investigalioijs. 

The  arrangement  here  proi>osed  diflers  radically  from  that  otTered  by  Mr. 
Wolliiston,  and,  if  found  in  accordance  with  natural  affinities,  will  result  in 
a  great  reduction  of  the  numlHir  of  genci-.i. 

The  geneni  I  recognize  in  our  fauna  are  as  follows:

HOMALOXBNUS  Wollaston. 

H.  dentipes  Woll.,  Tr.  Ent.  Soc.  London,  187*3,  015. 

Florida:  a  single  siieoimen,  collected  and  kindly  given  to  mc  by  Baron 
U.  Osten  Sacken,  agrees  so  perfectly  with  tlic  description  of  Mr.  Wollas- 
ton of  his  specimen  from  S.  Donjingo,  that  I  am  not  warranted  in  consid- 
ering it  as  distinct.  The  only  ditference  seems  to  be  that  in  my  specimen 
the  thighs,  tliough  verj'  thick,  are  hardly  percei)tibly  toothed;  this  chamc 
tcr  may,  however,  be  .sexual.  The  insect  will  be  easily  recognized  by 
the  very  depressed  form,  l)rown  color,  with  dull  lustre;  very  slender  beak, 
as  long  as  the  prothorax;  slender  antenme;  soircely  mucronate  tibia;,  end 
very  widely  dilated  and  bilolted  third  tarsal  joint;  characters  of  iiire  occur- 
rence in  the  present  sub-family,  but  combined  with  a  general  nppoaranc,' 
which  renders  the  afflnities  with  this  tribe  unmistakable. 

OOSSONUS  Clair V.  (emend.  Wollaston.) 

To  this  genus,  as  now  restricted,  belong  the  eight  species  comprised  in 
group  A,  Horn,  Pr.  Am.  Phil.  Soc.  437.  An  excellent  table  of  differences, 
also  the  bibliography  and  full  descriptions  are  there  given.  The  fuuicle  of 
the  antenna'  becomes  gradually  stouter,  and  the  dilatations  of  the  ajjcx  of 
tlie  beak  less  eviilent  from  the  first  species  (platalea),  to  the  eighth  (//«- 
pretxifrons),  thus  establishing  an  imperceptible  transitiim  to  Boropfilwus 
Woll.  So  far  as  I  may  judge  without  C(»mparison  of  speciuK'ns,  I  do  not 
see  why  B.  miiwr  Woll.  Trans.  Ent.  Soc.  London,  1873,  027,  may  not  be 
referred  to  the  species  determined  by  Horn  as  G.  corticola  Say. 

MAORORHYNCOLUS  Wollaston. 

To  this  genus  I  refer  the  Californian  Ehyneolax  protractux  Horn,  Pr. 
Am.  Phil.  Soc.  1873,  444,  which  ditlers  from  the  true  Uhyncoli,  not  only 
as  stilted  by  Horn,  in  tlu;  widely  sepanitod  front  coxa;  and  linear  form,  but 
by  the  longer  cylindrical  beak,  which  is  quite  distinctly  separated  from  the 
head.     The  third  joint  of  the  tarsi  is  narrow  and  fi  ebly  bilobed. 

MACRANOYLUS  n.  g. 

The  number  of  genera  in  this  tribe  has  been  increased  to  such  an  extent 
as  to  render  them  extremely  difHcult  to  recognize.  I  am  quite  unwilling  to 
add  to  the  names  already  published,  imtil  an  attempt  has  been  made  t(» 
combine  them  into  larger  groujjs.  It  is  for  this  reason  that  I  regret  to  pro- 
[)ose  this  genus  tor  an  extremely  slender  but  cylindrical  (not  depressed) 
BtHJcies,  which  has  the  beak  stout,  not  sepamted  from  the  front,  gradually 
but  slightly  tapering  externally.  The  antennal  grooves  commence  about 
the  middle  of  the  beak  and  the  anteniue  arc  inserted  b''hind  the  middle; 
the  scape  is  long,  extending  to  the  back  part  of  the  eyes,  and  is  rather  sud- 
d(!u'I5'  bent  and  thickened  from  the  middle  to  the  tip;  the  funicle  is  moder 
j.tely  stout,  the  first  joint  larger  and  thicker;  the  remaining  joints  short, 
closely  united,  gradually  but  very  slightly  broader;  club  oval,  pointed, 
rather  small,  distinctly  annulated  in  tlie  outer  half.     The  antennal  grooves

and  finely  t^ranulutcd.  The  front  coxa;  are  widely  scparaled;  Ihc  tibite 
gradually  dilated  and  the  front  pair  are  pubescent  towards  the  tip;  a  ilis 
linct  spine  is  seen  at  the  inner  apical  angle;  terminal  hook  long;  tarsi  with 
rather  broad  joints,  third  a  little  wider,  feebly  bilobed,  last  joint  longer 
than  the  others  united;  claws  large,  divergent.  Seutelluni  distinct,  elytra 
with  punctured  stria;,  which  are  deeply  impressed  near  the  tip. 

1.  M.  linearis,  n.  sp. 

Very  elongate,  cylindrical,  piceous  or  brown,  shining,  glabrous;  head  and 
beak  finely  punctured.  Prothorax  more  than  one  half  longer  than  wide, 
more  strongly  but  not  densely  punctured,  without  impressions;  slightly 
narrowed  in  front,  sides  nmndcd  near  the  base.  Elytra  not  wider  than 
prothorax,  stritc  coniposed  of  approximate  punctures,  deeply  exarate  on 
the  posterior  declivity  for  a  short  distance.  IJeneath  distinctly  but  finely 
punctured  ;  flanks  of  prothorax  feebly  concave  in  front.  Antenna;  and 
legs  reddish  brown.     Length  3  mm.;  .12  inch. 

Haulover;  Florida,  March:  Messrs.  Hubbard  and  Schwarz;  abundant  on 

the  sea  shon;;  no  sexual  differences  observed.     The  fifth  ventral  segment 

is  longer  than  the  third  and  fourth  united;  the  three  together  are  scarcely 

longer  than  the  first  and  second;  the  first  ventral  suture  is  obliterated,  even 

at  the  sides. 

ALLOMIMUS  n.  g. 

I  cannot  refer  Cossomm  dnbius  Horn,  1.  c.  442,  to  any  of  the  genera 
described  by  Wollaston.  It  is  nearly  alii  ^  to  Macranrydm,  but  is  of  less 
elongate  form,  and  very  much  more  coar  ,  y  sculptured;  the  elytra  are  in 
fact  rather  sulcate  than  striate,  though  the  deep  striie  ore  coarsely  punc 
tured,  and  the  interspaces  narrow  with  single  rows  of  small  punctures. 
The  beak  is  stout,  cylindrical,  a  little  narrower  than  the  head,  and  nearly 
as  long  as  the  prothorax;  the  antennal  grooves  cimimence  in  front  of  the 
middle,  and  run  directly  towards  the  eyes,  which  are  small,  rounded, 
moderately  convex  and  not  very  finely  granulated;  the  anlenniv  are  not 
very  stout,  the  scape  straight,  strongly  clavate,  extending  to  the  front  mar 
gin  of  the  eyes;  funicle  7-jointed,  first  joint  a  little  larger  and  stouter, 
remaining  joints  short,  closely  united,  gradually  but  slightly  broader,  club 
large,  oval-pointed,  pubescent,  ann'ilated.  Scutellum  distinct.  Front 
coxa;  widely  separated;  thighs  rather  stout,  tibia;  dilated,  with  a  small  spine 
at  the  inner  angle;  terminal  hook  long;  tarsi  with  the  third  joint  a  little

I    i 


The  genera  of  this  tribe  while  differing  from  those  of  the  Co»i>onini  only 
by  having  the  prosternum  very  narrow  between  the  coxa?,  and  by  having  a 
deep  transverse  gular  groove  beneath  in  front  of  the  eyes,  exhibit  other 
characters  which  slvow  a  strong  approximation  to  the  Scolytidoi ;  thus  i 
number  of  joints  in  tlie  funicle  of  the  antennue  varies  so  as  to  be  barely  of 
generic  value  ;  the  beak  becomes  very  much  sliortened,  and  the  head 
comparatively  larger,  as  in  Stenoscelin ;  the  form  of  the  club  varies, 
tiecoming  wedge  sliai)ed,  truncate  and  spongy  at  tip  in  WoUastonui,  thus 
iiicalling  tiie  form  seen  in  Iihynchophoru»,  &c.  ;  quite  rounded  or  i)erlia|;a 
a  littli!  transverse  in  Htenoscelis.  Tlie  form  is  also  that  of  certain  Scolylidir. 
Ithyntolut  resembles  closely  one  section  of  Ilylnstos,  while  Stenoscelis  \\x\9 
altogether  the  appearance  of  Hylurgopn  {II.  rugipennis,  &c.). 

As  in  the  Uhynchopliora,  from  the  nearly  jierfect  representation  of  past 
and  present  forms,  there  are  almost  always  intermediate  genera  to  be 
found,  I  would  say  that  Phhrophagus  seems  to  be  one  of  such  interme- 
diates, and  would  be  in  place  in  the  preceding  tribe,  if  I  did  not  regard  the 
approximate  front  coxa-  as  having  greater  systematic  value  than  the  longer 
beak  and  the  weaker  gular  groove. 

The  antennal  grooves  always  commence  near  the  ti))  of  the  beak  and 
descend  obliquely  below  the  eyes. 

Our  genera  may  be  separated  as  follows  ;

Tlie  Insects  of  this  family  are  mostly  of  cylindrical  form,  and  small  size- 
They  are  the  most  formidable  enemies  of  trees,  sometimes  devastating  the 
Ibrests,  especially  of  conifers,  by  appearing  in  incredible  numbers:  the  bur- 
rows are  cluetly  between  the  wood  and  the  bark,  though  some  genera  pene- 
trate mont  i\('c\)]y  (Xylotere^,  §r).  The  patterns  mad(!  by  them  arc  comphfx 
and  vary  according  to  genus  and  species;  those  of  several  EurojK'an  species 
arc  figured  in  the  excellent  work  of  Ratzeburg,*  and  since  descriptions  of 
our  siwcies  are  now  accessible,  so  that  tluiir  identiflcatlon  is  easy,  I  trust 
that  those  interested  in  the  preservation  of  our  forest  trees  may  direct  their 
attention  to  this  imiK)rlant  subject.  Specim  -ns  of  the  ravages  of  these  in- 
sects should  be  carefully  colletrted,  with  individuals  taken  from  the  bur- 
rows, and  these  should  be  dei)09ited  in  some  museum  where  they  will  be 
carefully  jireservcd  for  future  study. 

Since  the  publication  of  my  revision  of  this  family, f  a  few  additional 
species  have  been  found,  and  a  renewed  study  of  the  genera  has  rendered 
necessary  some  modilication  of  the  classification  there  proposed. 

The  great  dilferences  exhibited  by  Platypus,  and  its  allies,  indicate  the 
propriety  of  separating  them  as  a  distinct  sub-family,  a  course  already 
adopted  by  Lacordairc.

Sub-fiimily  II.     SCOLVTID-IS  (geimini). 

The  characters  by  whicli  this  sub- family  differs  from  the  Plati/podidieluwv 
been  already  sufflciently  pointed  out;  in  other  respe<'ts  tlie  species  ditfer 
greatly  according  to  genua  and  tribe,  and  the  chief  iKJCuliarities  will  be 
pointed  out  under  the  appropriate  lutads. 

The  genera  which  occurs  in  our  faima  indicate  the  following  tribes: 

1.  Prothorax  not  prolongcnl  over  the  head,  which  is  oblong 

and  prominent;  tai'si  with  fourth  joint  smaller  or  in- 
distinct; third  joint  usually  bih)bed t. 

Prothorax  prolonged  over  the  head,  which  is  deeply  im- 

mersed  and  globose;  tarsi  filiform,  5  jointed TOMlt'i^vl. 

2.  Ventral  surface  ascending  ol)li(iuely Ki'Ol.VTl.<VI. 

"  "      regularly  cylindrical IIYI.KMI.VI. 

Tribe  I.     tomicixi. 

Although  the  genera  of  this  iribo  are  the  farthest  removed  from  Con- 
Honidie  by  their  characters;  they  are  in  some  respects  the  most  nearly  allied 
to  Plttlypun,  with  which  the  family  must  naturally  commence,  on  account 
of  the  relations  between  the  latter  and  JRrenthida. 

The  head  is  globose,  or  nearly  so,  and  deeply  immersed  in  the  i)rothorax ; 
the  eyes  are  transverse,  sometimes  divided,  (Xi/loleru»):  the  front  is  not 
prolonged  into  a  beak;  the  antennte  are  inserted  near  the  base  of  the  man 
dibles;  the  scajie  is  long  and  stout,  the  funicle  short,  coni|)osed  of  from  one 
to  five  joints,  the  mass  large,  compressed,  varying  in  form  and  structure  ac- 
cording to  genus.  Prothorax  more  or  less  cylindrical  behind,  prolonged  in 
front  over  the  hi-ad  aid  much  rounded,  so  that  the  anterior  ope  liiig  be 
c)mes  very  oblii|ue,  or  even  s  )metimi's,  ahn'>sr  horizuiUii;  t'le  .sculpture  is

granules,  or  little  spines;  behind,  the  surface  is  smooth  or  j-unctured;  the

head  nearly  smooth,  broadly  and  deeply  concave,  thinly  fringed  with  not 
very  long  yellow  hair.  The  species  is  easily  recognized  by  the  large  ellij)- 
tical  i)atch  of  yellow  hair  each  side  of  the  prolhorax,  and  by  the  tine  dis 
tant  rows  of  elytral  punctures;  the  declivity  is  not  retuse,  and  the  sutural 
.stria  is  deeply  impressed.  The  club  of  the  antennu'  is  divided  by  three  dis- 
tinct straight  sutures.  I  am  not  certain  of  the  numbir  of  divisions  in  the 
oviter  part  of  the  funide.     Length  1.8  mm.;  .07  inch. 

It  is  i)ossible  that  P.  infam  Eichhotf,  Berl.  Ent.  Zeitsch,  1871.  135,  may 
be  the  J  of  this  species.  It  is,  however,  unknown  to  me,  and  1  have  seen 
nothing  that  corresponds  with  the  description. 

HYPOTHENEMUS  Westwood. 

The  species  I  refer  to  this  genus  agree  in  having  the  outer  part  of  the 
funiclc  of  the  antennas  very  short,  shorter  in  fact  than  the  first  joint,  and 
very  indistinctly  divided;  in  the  first  species  only  by  one  transverse  suture; 
but  in  11.  disiimilis,  the  divisions  seem  mori'  niunerous,  probably  three, 
but  so  indistinct  that  they  are  without  value.  The  head  is  larger  and 
more  cxserted  than  in  tlu^  preceding  genera;  eyes  narrowly  emarginate, 
the  club  of  the  antennte  is  round,  compressed,  moderate  in  size,  and  di 
vided  by  straight  sutures  on  both  sides.  The  tarsi  are  distinctly  ."i-jointed, 
the  third  joint  rather  longer  than  the  first  or  second;  the  fimrth  small  as 
usual;  fifth  elongate.  The  tibite  are  distinctly  serrate  towards  the  tip.  The 
declivity  of  the  elytra  is  not  retuse  or  sulcate. 

A.  Body  cylindrical,  asperities  of  prothorax  acute  and  numerous.

The  insects  of  this  group  are  rather  robust  and  cyliiulrical  ;  the  declivity 
of  the  elytra  is  oblique,  not  excavnted  and  not  toothed.  The  eyes  are 
comjdetely  divided,  and  the  club  of  Ww.  antennaj  is  oval,  solid,  pubescent 
on  both  sides,  and  not  annulated.  The  tibia;  are  broad,  roundtsd  at  tip, 
and  serrate  on  the  outer  and  terminal  edge.  The  tarsi  are  slender,  the 
fourth  joint  small,  as  usual,  and  the  fifth  long,  with  simi)le  divergent

by  anastomosing  rugie,  and  the  front  part  is  as  rough  as  in  the  9  of  X.  bi-

I  have  received  specimens  from  Mr.  J.  A.  Linlner,  as  depredating  ujwn 
maple  trees.  Easily  known  by  being  more  hairy  than  the  other  species, 
with  the  interspaces  of  the  elytra  sparsely  punctured,  so  that  the  rows  of 
punctures  appear  confused.  I  observe  no  sexual  difterence  in  the  specimens 
before  me,  and  the  species  may  readily  t)e  separated  as  a  distinct  genus,  by 
any  one  who  will  avail  himself  of  the  characters  in  the  antennal  club, 
which  I  have  pointed  out  above.

me,  but  seems  to  be  allied  to  X  politus. 

Group  III.  Xylebori. 
The  essential  character  of  this  group  is  that  the  club  of  the  antennro  is 
entirely  corneous,  and  not  articulated  on  the  inner  surface;  on  the  outer 
surface  it  is  also  corneous,  except  towards  the  distal  end,  where  it  is  ob- 
liquely truncsite;  the  truncate  surface  is  pubescent  and  sensitive,  and  has 
three  concentric  or  transverse  sutures,  which  indicate  the  other  joints  of 
the  club  The  scape  of  the  antennie  is  elongate,  and  the  funicle  usually 
distinctly  .T-jointed,  though  in  some  species  there  appear  to  be  but  four 
joints.  The  tibiaj  are  dilated,  more  or  less  serrate,  and  spinose  on  the  outer- 
margin,  with  the  apex  obtusely  rounded,  and  the  inner  angle  not  very 
strongly  ungtiiculate.  The  tarsi  are  slender;  fourth  joint  small,  fifth  nearly 
as  long  as  the  others  united;  claws  strong,  divergent,  simple.

The  species  of  this  groui)  are  of  C3iindrical,  but  not  very  slender  form, 
and  are  easily  recognized  bj'  the  deeply  excavated  elytral  declivity,  which 
is  shari)ly  margined  and  acutely  toothed.  Tlie  club  of  the  antennre,  as  in 
the  group  Xylebori,  is  entirely  corneous  on  the  inner  face,  but  is  not  ob- 
liquely truncate  on  the  outer  face.  The  sensitive  surface  is  more  or  less 
distinctly  defined,  and  is  divided  by  two  sutures  which  are  more  or  less 
curved  or  angulated  in  our  species,  but  are  described  in  some  European 
species  as  straight,  thus  showing  an  affiliation  with  Dryocietes  of  the  prece- 
ding group.  The  tibiffi  are  coarsely  serrate,  and  the  tarsal  joints  1-3  are 
rather  stouter  than  in  the  preceding  groups. 

Our  species  represent  l)ut  one  genus,  which  m'\y  be  divided  conveniently 
according  to  the  form  of  the  sutures  of  the  antennal  club.

and  are  quite  like  those  of  the  European  T.  stenographv,i ;  which  dirt'ors 
bj'  its  larger  size,  more  coarsely  punctured  prothorax,  and  especially  by 
having  but  two  teeth  on  the  edge  of  the  elytral  declivity  behind  the  most 
prominent  tooth. 

For  the  purpose  of  making  the  distinc  tions  between  the  species  mentioned 
below  more  intelligible,  I  will  describe  the  arrangement  of  the  teeth  in 
this  species,  in  which  the  number  is  greatest.  The  declivity  is  deeply  con 
cave,  polished,  sparsely  jiunctured,  and  the  prolongation  of  the  sutural 
stria  is  well  impressed.  At  the  posterior  end  of  the  second  interspace  is  a 
small  cusp,  and  a  similar  one  at  the  end  of  the  third  intersjiace  ;  these  two 
small  cusps  or  denticles  are  not  mentioned  in  the  synoptic  table  given 
above.  At  the  end  of  the  fourth  interspace  is  a  large  conical  tubercle, 
which  in  this  species  is  but  slightly  connected  with  the  tubercle  of  the  fifth 
interspace,  which  in  always  the  most  prominent.  Behind  this  prominent 
one  there  are  in  the  present  species  three  acute  equidistant  teeth,  and  the 
ajiical  acutely  elevated  margin.  The  disappearance  of  some  of  these  teeth 
in  the  following  species  is  produced  by  their  absorption  in  the  acute  ter 
minal  margin,  which  thus  becomes  longer,  so  that  in  T.  pini  it  extend."* 
around  fully  one-third  of  the  declivity.

The  dimensions  and  relations  of  these  teeth  with  each  other,  and  the 
arrangement  of  the  sutures  of  the  antennal  club  give  excellent  characters 
for  the  discrimination  of  the  species  ;  and  I  hope  that  the  student  will  have 
no  difficulty  in  recognizing  those  I  have  admitted  in  this  memoir.  The 
descriptions  of  those  named  by  Mr.  Eichhotf  are,  however,  too  indefinite 
for  me  to  venture  to  pronounce  with  certainty  upon  their  affinities  ;  they 
seem,  moreover,  if  I  may  Judge  from  the  short  diagnoses,  to  have  been 
unduly  multiplied  upon  individual  differences  of  slight  importance.

Southern  and  Western  States.  Similar  to  the  preceding,  but  usually  of 
.smaller  size,  (3.5-4  mm.;  .14-.16  inch);  the  cusp  of  the  second  interspace 
is  very  small,  anil  that  of  the  third  is  wanting  ;  that  of  the  fifth  is  com 
pressed  and  scarcely  more  prominent  than  that  of  the  fourth  interspace 
and  is  somi-wh.it  connected  with  it ;  there  are  but  two  teeth  between 
the  tooth  of  the  fifth  interspace  and  the  terminal  acutely  elevated  margin, 
and  thes(!  teeth  are  all  of  them  less  prominent  than  in  T.  calligraphus,  in 
some  specimens  (J^),  but  equally  jirominent  in  others,  9>  those  less  acute 
than  in  T.  enUgraphus.  The  interspaces  from  the  third  outward  are 
marked  eacli  with  a  regular  series  of  punctures  behind  the  middle,  whereby 
it  diflfers  from  the  next  species.  Tiie  club  of  the  antenna;  is  quite  similar  to 
that  of  T.  CAilligraphuK. 

3.  T.  confusus,  n.  sp. 

Quite  like  T.  cucographux,  except  that  the  elytral  strite  are  composed  of 
larger  and  more  transverse  punctures  ;  the  punctuies  of  the  interspaces  are 
very  distant  as  far  as  the  middle,  but  become  irregular  and  confused  with 
tiie  strire  behind.  The  teeth  on  the  margin  of  the  declivity  are  arranged 
just  as  in  T.  cacographus,  but  are  larger  and  stouter,  and  the  one  of  the 
fifth  interspace  has  a  tendency  to  become  curved  at  the  end.  The  club 
of  the  antennie  as  in  the  two  preceding  species.     Length  4  mm. ;  .16  inch.

4.  T.  plastographus  Lee,  Tr.  Am.  Ent.  Soc.  1868,  163. 

Middle  California  and  New  Mexico  ;  two  specimens.  This  species  closely 
resembles  T.  confusus  in  the  sculpture  of  the  elytra,  the  interstrial  punc- 
tures being  confused  behind,  but  on  the  inner  interspaces  from  the  third  to 
the  fifth  there  are  no  punctures  except  near  the  declivity.  The  tooth  of  the 
fourth  interspace  is  more  compressed  and  closely  united  with  the  very 
prominent  tooth  of  the  fifth  interspace,  which  is  cylindrical  and  obtuse  ; 
there  is  but  one  tooth  between  that  of  the  fifth  interspace  and  the  apical 
elevated  margin,  but  this  is  large  and  conical.  The  sutures  of  the  antennal 
club  are  very  strongly  angulated.     Length  4.5  mm.;  .18. 

5.  T.  emarginatus,  n.  sp. 

Cylindrical,  shining,  ])lacki8h  piceous,  sparsely  clothed  with  long  yel- 
lowish hairs.  Head  granulated,  with  two  small  frontal  elevations,  the 
anterior  one  near  the  margin,  which  is  fringed  as  usual  with  short  yellow

broadly  rounded,  margined  only  near  the  side  ;  anterior  half  of  disc 
asperate  with  granules ;  posterior  half  strongly  and  tolerably  densely

posed of  strongly  impressed  transvc^rse  punctures,  interspaces  wide,  1-7 
smootli  except  near  the  declivity,  where  there  are  a  few  punctures  ;  outer 
interspaces  witii  i)unctures  gradually  becoming  contused  near  the  sides ; 
declivity  deeply  concave,  strongly  and  coarsely  punctured,  with  the 
sutural  stria  deeply  impressed ;  the  teeth  of  the  second  and  third  inter- 
simces  are  small,  but  acute  ;  that  nf  the  fourth  is  larger,  coni('al  and  sub- 
acute ;  that  of  the  tifth  is  large,  compressed  and  emarginate  ;  the  inter- 
val between  it  and  the  apical  elevated  margin  is  wide,  and  in  some  speci- 
mens is  marked  by  a  single  indistinct  cusp  ;  the  apical  margin  is  long,  and 
its  anterior  angle  is  more  i)rominent  than  usual  ;  the  sutural  angle  is 
slightly  prominent,  as  is  frequently  the  pase  in  other  s|)ecies,  a  character 
of  no  importance.  The  sutures  of  the  antennal  club  are  nearly  straight, 
slightly  bent  forwards  at  the  sides.  Length  6.0  mm. ;  .20  inch.

0.  T.  rectus,  n.  sp. 

This  species  resembles  the  preceding  in  form  and  color  ;  but  is  of  smaller 
size,  and  the  prothonix  is  less  decsply  punctured  behind,  with  a  distinct 
smooth  medial  space.  The  elytral  stria;  and  interstrial  punctures  are 
similar,  but  the  teeth  of  the  declivity  are  ([uite  dilferent ;  the  cusi)s  of  the 
second  and  third  interspaces  are  small,  but  distinct  and  acute  ;  that  of  the 
fourth  is  broad,  compressed  and  closely  united  with  that  of  the  fifth,  which 
forms  a  prominent  tooth  at  its  posterior  extremity,  the  anterior  extremity 
of  this  conjoined  mass  is  not  acute,  but  barely  rectangular,  and  the  apical 
acute  margin  is  a  rather  large  acute  tooth.  The  body  is  thinly  clothed 
with  long  yellow  hair,  especially  in  front  and  behind.  The  antennal  club 
is  marked  with  three  sutures,  the  first  and  second  curved  at  the  middle, 
bent  forwards  at  the  side,  and  the  third  nearly  straight.  Length  4  mm.; 
.11  inch. 

One  specimen,  New  Mexico  and  two  from  Oregon.  I  should  consider 
these  as  badly  developed  specimens  of  T.  plastographus,  except  for  the  dif- 
ferences in  the  antennal  club.

The  elytral  striie  are  composed  of  small,  transverse  punctures;  the  inter- 
spaces are  wide  and  flat,  and  are  nuirked  with  only  a  few  punctures  near 
the  declivity;  the  latter  is  deep,  strongly  punctured,  as  in  all  the  preceding 
species,  with  the  sutural  stria  deeply  impressed;  the  tooth  at  the  end  of  the 
second  interspace  is  small,  but  acute  and  distinct;  that  of  the  third  is  want- 
ing; that  of  the  fourth  and  fifth  are  acute,  and  connected  by  an  elevated 
ridge,  behind  them  there  is  one  acute  compressed  tooth,  which  is  .scarcely  less 
prominent,  and  this  is  followed  after  a  narrow  interval  by  the  apical  margin.

Hudson  Bay  Territory.  Harris,  who  is  good  authority  upon  Say's  species, 
ii'iiicates  tliis  as  the  one  described  by  that  author.  It  is  destructive  to 
Nortliern  i)ine  foreats  in  the  same  manner,  but,  as  far  as  observation  yet 
goes,  to  a  less  extent  than  T.  cdcographus  is  in  the  South.  I  have  tiicre- 
foro  felt  warranted  in  rejecting  Dr.  Zimmermann's  determination  of  Say's 
species,  and  liave  ai)plied  a  dill'erunt  name  to  the  insect  which  has  caused 
so  great  destruction  to  the  pine  forests  of  tlie  Southern  States.

Specimens  of  a  larger  size  (5  nun.:  .10  in.),  from  Hudson  Bay  Terri-

thiclicr  and  curved.  I  would  be  unwilling  to  designate  it  by  a  separate

at  the  sides,  but  are  nearly  straight.

The  scutellum  is  described  by  Eichhoff  as  smooth,  but  in  my  specimens 
it  is  as  distinctly  channeled  as  in  the  five  specimens  of  T.  interruptua;  as  in 
fact  it  is  in  all  the  preceding  species  except  T.  calliffrapJius  and  marginatut; 
this  channel  is  less  distinct  in  T.  plastographua  than  in  the  others,  but  at 
best,  is  an  illusive  character  of  but  little  worth. 

Alaska,  one  specimen.  Very  similar  to  T.  interruptxn,  but  the  punctures 
of  the  elytral  striue  are  larger  and  more  distant,  and  those  of  the  interspaces 
nearly  as  large,  though  less  numerous.  The  head  is  more  finely  granulate, 
strongly  retuse  in  front,  with  a  broad  frontal  groove.  This  character  is  prob- 
ably sexual  rather  than  specific.

Alaska,  three  specimens.  Length  4.2  mm.;  .17  inch.  A  very  distinct 
species,  with  tlie  elytra  confusedly  punctured;  tlie  declivity  obliipie,  nearly 
flat,  punctured,  with  the  sutural  stria  scarcely  distinct;  the  teeth  are  but 
three  each  side,  of  which  the  anterior  one  is  small,  and  the  third  longer 
and  larger  than  the  second. 

Group  V.     Micracldes. 

The  funicle  of  the  antennae  is  C-jointed,  the  outer  joints  broader;  the  club 
is  pubescent  and  usually  marked  with  sutures  on  both  sides,  as  in  the  group 
Gorthyli,  but  these  sutures  are  usually  very  much  curved,  though  some 
times  nearly  straight  ;  the  basal  joint  is  long,  and  in  one  sex  is  fringed 
on  the  front  margin  with  very  long  hairs ;  the  eyes  are  transverse, 
coarsely  granulated,  either  distant  or  contiguous  beneath.  The  protho- 
rax is  produced  over  the  head,  rounded  and  asperate  in  front,  and  its 
anterior  opening  is  very  oblique  as  in  most  Pttyophthori.  The  elytra 
are  usually  punctured  in  rows,  convexly  declivous  behind,  then  con 
cave  near  the  tip,  and  sometimes  asperate  with  small  gr^ules  ;  the 
suture  is  produced  into  a  sharp  point,  except  in  T.  fimbricornis-  The  tibiie 
are  compressed,  armed  with  a  terminal  hook,  outer  edge  acute,  not  at  all 
toothed  (or  but  slightly  so  in  M.  rudis),  and  fringed  with  long  hair;  the 
front  pair  are  as  broad  at  base  as  at  tip  ;  the  joints  of  the  tarsi  1-3  are 
rather  stout  in  all  the  species  except  J/,  hirtella,  where  they  are  longer  and 
more  slender,  the  fourth  joint  is  small,  and  the  fifth  long,  slender,  with 
divergent  simple  claws.  Although  important  structural  differences  are 
seen  in  the  species,  I  regard  them  as  constituting  but  two  genera.  This 
group  is  excellently  defined  by  the  O-jointed  funicle,  and  the  broad  parallel 
front  tibiae.

more  distant,  and  from  tliem  proceed  short,  clavate,  pale  bristles  in  regular 
rows;  declivity  convex,  not  at  all  impressed  or  retuse,  sutural  line  very

Lancaster  County,  Pennsylvania.  Abundant  in  twigs  of  hickory;  easily 
recognized  by  the  characters  given  above.  The  first  and  second  ventral 
segmcnis  are  each  as  long  as  the  others  united;  third,  fourth,  and  fifth  short, 
equal,  last  dorsal  sligh'.ly  visil)le  from  beneath.  The  bristles  are  not  striate 
as  in  Ilj/pothenemm,  but  linely  granulated. 

Tribe  IL     s€OI.YTI9ri. 

The  species  of  this  tribe  are  easily  known  by  the  peculiar  conformation 
of  the  ventral  surface,  which  is,  namely,  flattened  or  concave,  and  obliquely 
ascending  from  the  posterior  end  of  the  first  segment  to  the  fifth  ;  the  first 
and  si'cond  segments  are  closely  connate,  and  the  other  three  are  separated 
by  straight  sutures,  about  equal  in  length,  and  united  are  hardly  longer 
than  the  oblique  part  of  the  second  segment.  The  antennal  club  is  pubes- 
(ient  on  both  sides,  nearly  solid  and  marked  with  indistinct  but  strongly 
(Uirved,  or  rather  angulated,  sutures;  the  scape  is  short,  the  first  joint  of 
the  funicle  rounded,  the  remaining  joints  (five  in  number)  closely  united 
forming  a  pedicel  to  the  club.  The  thighs  are  stout,  the  tibioe  rather  broad 
and  compressed;  the  front  pair  are  not  serrate  on  the  outer  edge,  which  is 
(juite  sharp  ;  the  outer  apical  angle  is  armed  with  a  long  curved  hook,  and 
the  inner  angle  is  nearly  rectangular  but  not  armed  with  a  spine  ;  the  outer 
margins  of  the  middle  and  hind  tibitii  are  feebly  serrate,  they  are  truncate 
at  tip,  and  armed  with  two  spines  or  spurs  at  the  outer  angle,  and  a  much 
smaller  spine  at  the  inner  angle  ;  the  tarsi  are  slender,  as  long  as  the  tibine  ; 
the  third  joint  is  deeply  bilobed,  the  fourth  small,  the  fifth  long,  with 
simple  divergent  claws. 

The  side  margin  of  the  prothorax  is  distinctly  defined,  a  very  rare 
cliaraeter  in  Rhynchophora,  and  the  front  coxie  are  separated  by  the  pro- 
sternum,  which  is  very  short  in  front  of  the  coxie.  In  some  ot  the  species 
the  ventral  segments  of  the  ^f  are  ornamented  with  spines,  or  acute  tuber- 
cles such  as  have  been  already  mentioned  in  Proctorun  (p.  212)  and  Pla- 
typus  (p.  lUIl). 

But  one  genus  represents  this  tribe.

and  in  Ilylastes  assume  very  much  the  same  form  as  in  Conxonidie,  to 
wliicli  some  of  lljcse  insects  boar  a  stnmg  resemblance.  Tliey  may  l)e  dis- 
tinguislied,  liowever,  by  the  conipressed  and  serrate  or  spinulose  tllna'. 

Tlie  third  joint  of  the  tarsi  is  frequenlly  dilated  and  bilobed,  and  the 
fonr;h  joint,  less  connpicuous  than  in  the  preceding  tribes,  is  sometimes 
qiite  indistinct.  The  first  and  second  ventral  segments  are  always 
separated  by  a  well-defined  straight  suture,  more  deeply  impressed  than  in 
Tom'cini. 

The  prothora.v  is  bisinuate  behind,  with  a  well  defined  antescutellar 
angle  in  some  of  the  species  of  all  the  groups  except  Ilylastes.  They  thus 
manifest  a  tendency  to  the  J./i^Ar/ft/rfte  [Ghorayus,  &c.),  as  Ilylastes  does 
towards  the  Cossonidm. 

In  several  genera  the  front  co.\nj  are  separated  by  the  prosternum,  and 
in  Dendi'octonus  and  the  allied  Europoa'.i  genera  Ilyliirgm  and  Blastopha- 
giis  the  second  and  third  ventral  sutures  ire  curved  backwards  at  the  sides. 
In  Ilylastes  the  prosternum  is  deeply  e.vcavated  for  the  reception  of  the 
short  beak.  In  all  these  characters  resemblances  are  seen  to  different 
tribes  of  CurcuUonidm.

Group  I.     Polygraphl. 

This  group  is  sufficiently  defined  by  the  club  of  the  antenme  being  large, 
strongly  compressed,  pubescent  and  sensitive,  and  without  sutures  on  both 
sides,  and  by  the  antennre  being  inserted  as  usual  at  the  sides  of  the  front. 
The  tibiic  are  broadly  dilated,  obliquely  rounded  at  the  ajiex,  and  finely 
serrate  ;  th  j  third  joint  of  the  tarsi  is  not  bilobed,  and  the  fourth,  though 
small,  is  distinct.     The  basal  margin  of  the  elytra  is  acute  and  serrate.

ditlers  from  both  by  the  antennal  club  beiag  composed  of  three  sei>arate 
joints,  which  in  Phlceotribus  form  a  lamellate  ma  s,  and  in  the  European 
genus  PhlmophtJwrus  a  loosely  articulate  club  as  in  many  Clavicornia.  Dr. 
C  lapuis  describes  the  antennte  as  frontal  ;  but  I  see  no  special  difference 
i  I  their  position  from  that  observed  in  the  preceding  and  following  groups. 
The  head  is  but  very  little  prolonged  in  front  of  the  eyes,  and  there  is  no 
preocular  groove  for  the  reception  of  the  scape  of  the  antenna;  such  as  is

mandibles  are  stronger,  nearly  flat  above,  and  tlu!  labruni  is  obsolete;  these 
characters  indicate  a  recurrence  towards  the  normal  Kh^ncbophora.  The

I  have  already  sufficiently  described  this  remarkable  genus,  which  is  at 
once  known  by  the  widely  separated  front  coxa;,  and  the  longitudinally 
aciculate  prothorax.  Dr.  Chapuis  is  in  error  in  describing  the  tibiiC  as 
"extus  imegerrima;;"  the  front  tibiie  have  three  acute  teetli  directed  back- 
wards, of  which  the  third  is  apical,  and  the  others  near  the  apex ;  the 
outer  apical  angle  of  the  middle  tibite  is  produced,  and  emarginate  at  tip. 
The  third  joint  of  the  tarsi  is  visible  but  not  conspicuously  emarginate;  the 
joints  1-3  are  rather  stout,  nearly  equal,  and  the  fifth  is  shorter  than  the

depth  or  punctuation  of  the  elytral  striie  as  to  warrant  the  diflerential 
phrases  used  by  Dr.  Chapuis.  It  is  found  also  in  Wisconsin  and  Georgia,  ac-

ing species.

So  far  as  the  distinctions  exist  between  this  and  the  preceding,  they  arc 
well  exhibited  in  the  descriptions  of  Eichhoff;  to  whom,  however,  the  de- 
scriptions of  Say  seem  to  have  been  unknown.  It  has  happened  unfor- 
tunately that  Dr.  Chapuis  has  applied  Say's  name  to  the  less  known  form 
called  imperialis  by  Eichhoff,  and  retained  j»'ui>iosii,s  for  the  present  well- 
known  and  widely  diffused  form. 

The  Munich  Catalogue  has  added  to  the  confusion  by  citing  Say's  de- 
scription under  the  genus  Bendrosinus  (2073),  and  placing  II.  ijlobosus 
Eichhoff,  as  a  synonym.  The  latter  is  probably  a  South  American  sjiecies, 
described  by  Eichhoff,  with  an  incorrect  locality,  since  a  variety  of  it  is 
mentioned  by  Chapuis  (p.  28)  as  occurring  in  Columbia.  Length  2.2-

ditference.  The  elytra  are  not  banded  as  in  the  preceding  species,  but 
confusedly  tesselated.  I  observe  no  sexual  characters,  and  the  front  is 
finely  carinate  in  the  four  specimens  examined.  The  head  is  more  prolonged

Middle  States.  This  species  has  a  deceptive  resemblance  to  Phlcpotribus

tainty be  separated.  The  reference  to  the  genus  Phlteosinus  is  incorrect, 
as  the  outer  part  of  the  tunicle  is  divided  into  six  joints  by  five  transverse 
sutures,  precisely  as  in  the  other  species  of  IIylesinu».  The  club  is  sub- 
ovate,  obtusely  pointed,  with  straight  sutures,  and  the  basal  part  is  more

In  this  genus  the  funicle  of  the  iintennie  is  much  sliortcr  than  the  club, 
the  rtrnt  joint  is  rouniled,  the  remaining  four  joints  are  tlosely  united  and

rounded,  and  divided  by  straight  well-marked  sutures.  The  front  coxie 
are  moderately  distant.  The  tlbiie  are  acutely  serrate  ;  the  tarsi  have  the 
joints  1-3  equal,  the  third  bilobcd  ;  the  fifth  is  nearly  equal  to  the  others

necessary  to  distinguish  it  from  the  common  and  well  known  P.  dentatus. 
Any  lengthy  descrip'.ion  would  be  unnecessary,  as  it  only  dilfcrs  by  larger 
size,  and  by  the  first  and  third  interspaces  being  strongly  elevated  and  ser- 
rate behind.  The  pubescence  is  shorter,  and  seems  less  dense  than  in  P.

synonym  to  any  of  the  species  above  described;  being  from  Texas  it  is 
quite  likely  to  be  dillerent.  The  descriptions  of  both  these  species  will  be 
found  in  the  appendix. 

OHwffiSTOPHLCBUS  n.  g. 

This  genus  is  founded  upon  IIyleninn»  hyntrix,  a  singular  species  from 
California,  of  robust  oval  form,  thickly  clothed  with  coarse,  erect  hair.  It 
differs  from  PhlaoHinifi  by  the  four  joints  which  constitute  the  outer  part 
of  the  funicle  of  the  antennic  being  slender,  and  increasing  much  less  rap- 
idly in  thickness;  tlie  club  is  equally  large,  subovate,  compressed,  obtusely 
rounded  at  tip,  and  the  sutures  are  also  straight.  The  mouth  is  clothed  with 
long,  coarse  hair.  The  prosternum  is  very  short  in  front  of  the  coxa?,  which 
are  very  narrowly  separated.  The  first  ventral  segment  is  longer  than  the 
second,  and  the  third,  fourth  and  fifth  are  short.  The  tibiic  are  broadly  di- 
lated, rounded  and  finely  serrate  at  tip;  the  tarsi  are  not  plainly  visible  in 
the  unique  specimen  in  my  collection,  but  the  third  joint  is  emarginate, 
rather  than  bilobed.

San  Diego,  one  specimen.  The  head  is  broadly  concave,  with  a  smooth 
medial  line.  The  prothorax  is  strongly  and  densely  punctured.  The  elytral 
striic  are  not  impressed,  and  arc  composed  of  approximate  punctures;  the 
interspaces  are  flat,  punctured;  the  declivity  is  rounded,  the  part  near  the 
suture  is  deeply  and  broadly  concave,  and  the  outer  side  of  the  concavity, 
corresponding  to  about  the  fourth  interspace,  is  armed  with  four  or  five  tu- 
bercles; the  sutural  interspace  on  the  declivity  is  narrow,  slightly  elevated, 
and  marked  with  a  row  of  very  small  granules.  Length  2.2  mm. ;  .09  Inch.

second  less  evidently  narrowed.  The  punctures  of  the  elytral  striae  are

Canada,  Georgia,  Oregon,  California.  The  specimens  from  tlie  Pacific 
slope  are  larger,  and  the  punctures  of  the  prothorax  are  rather  smaller  and 
more  dense,  but  these  differences  do  not  seem  to  me  worthy  of  specific 
distinction.  Some  specimens  from  New  Hampshire  and  Canada  have  the 
prothorax  more  spai-sely  punctured,  almost  as  in  the  next  species,  from 
which  they  are  only  distinguished  by  the  shorter  hairs  of  the  elytra. 
Length  5.2-8  mm  ;  .2-. 33  inch. 

2.  D.  similis  Lee,  Pac.  R.  R.  Expl.  and  Surveys,  Ins.  59. 

Oregon  ;  five  specimens.  I  have  incorrectly  cited  tliis  species  as  a  syn- 
onym of  D.  obesus,  from  which  it  differs  in  having  the  aspeiities  of  the 
elytra  continue  on  the  declivity.  The  tibia'  are  armed,  as  in  the  preceding, 
with  three  acute  teeth  on  the  outer  "ide  near  the  tip,  but  the  prothorax 
is  less  densely  punctured,  and  the  elytral  hairs  are  longer  ;  the  back  part  of 
the  head  is  less  densely  punctured.     Length  4.5-0.5  mm.;  .18-.25  inch. 

A  smaller  and  somewhat  more  elongate  form  occurs  in  Canada,  Texas 
and  Colorado,  but  I  do  not  think  it  capable  of  being  separated  as  a  distinct 
species.     Length  4.2  mm. ;  .165  inch.

Alaski,  Canada,  Anticosti.  I  can  perceive  no  difference  between  the 
specimens  sent  me  under  the  names  cited  above.  It  is  only  to  be  distin- 
guished from  the  preceding  by  the  declivity  of  the  elytra  smoother  and 
more  shining,  and  almost  without  asperities  ;  and  by  a  slight  difference  in 
the  punctures  of  the  prothorax,  which  are  of  unequal  size.  The  dorsal 
line  of  the  prothorax  is  sometimes  narrow  and  elevated,  sonietimesobsolcte.

New  York;  three  specimens.  Very  similar  to  the  preceding,  but  the 
back  part  of  the  head  is  nearly  smooth,  or  feebly  punotulate  ;  the  punctures 
of  the  prothorax  are  larger  and  les"  dense,  and  the  declivity  of'the  elytra 
less  shining,  and  very  slightly  asperate.     Length  6  mm. ;  .25  inch.

more  shining,  and  more  strongly  and  spai-sely  punctured  on  the  declivity; 
tbi;  head  is  sparsely  but  deeply  punctured  heliind,  and  in  front  is  densely

Lake  Superior  to  Georgia.     The  head  is  channeled  and  marked  with 

approximate  frontal  tubercles ;  the  occiput  is  finely  punctulate,  the  front 
roughly  punctured  as  usual.  The  interspaces  of  the  declivity  of  tlie  elytra 
are  finely  asperate,  and  the  hairs  are  short.  The  prothorax  is  scarcely 
narrowed  in  front,  and  the  base  is  more  strongly  bisinuate  tlian  in  the  other 
species.  Tlie  clul)  of  the  antenna;  is  round,  strongly  compressed  and  con- 
cave on  one  side,  as  in  the  other  species;  and  tlie  sutures  are  not  straight, 
but  curved.     Length  3  mm. ;  .12  inch. 

The  frontal  channel  is  deeper,  and  the  granulate  punctures  larger,  and 
denser  in  one  sex  than  in  the  other.

BLASTOPHAGUS  Eichhoff. 
This  genus  does  not  i)ropevly  belong  to  our  fauna,  and  I  mention  it  only 
for  tlie  purpose  of  correcting  the  error,  which  I  committed  of  describing

pared it  with  the  Turopean  //.  lign'perda  on  theauthority  of  an  incorrectly 
named  specimen  which  I  borrowed  for  comparison.  If  the  genus  should

of  the  funicle  of  the  antunna;  being  divided  into  T^  joints,  tluis  making  the

Group  IV.     CryptiirKl. 

This  group  consists  of  two  genera,  represented  by  very  small  species  uf 
elongate  form,  which  agree  with  JfifliisteH  In  general  appearance  and  sculp- 
ture, but  differ  by  the  beak  being  much  shorter,  and  the  prosternuni  very 
short  and  not  excavated.  The  genus  Grypturgun  has  been  usually  associated 
with  the  Tomic!ni,  on  account  of  the  slender  tarsi,  but  it  makes  a  notable 
exception  to  the  other  members  of  that  tribe  by  the  large  exserted  head, 
and  the  absence  of  the  hood-like  prolongation  of  the  pro'horax.  I  have, 
therefore,  thought  it  best  to  remove  it  ffom  that  position,  and  place  it  with 
Dolurgus,  as  a  separate  group.  Though  dill'ering  in  the  antcnnal  club, 
which  is  solid  in  Crypturgun,  and  annulated  transversely  with  the  lirst 
joint  corneous  in  Dolargas,  these  two  genera  are  otherwise  closely  related, 
and  differ  remarkably  from  neighboring  forms  by  the  small  number  of 
joints  in  the  funicle.  The  prothorax  is  ehmgateoval,  rounded  in  front, 
nearlj'  truncate  at  base;  the  scutcllum  is  very  small,  not  depressed,  and  the 
basal  edge  of  the  elytra  is  not  elevated.  The  elytra  are  elongate-cylindri- 
cal, with  the  posterior  declivity  convex;  the  striaj  are  well  marked,  and 
strongly  punctured;  the  interspaces  narrow,  finely  punctulate  and  sligiitiy 
pubescent.  The  ventral  sutures  are  straight  and  deep;  the  first  and  fifth 
segments  are  longer  than  the  others.  The  prosternuni  is  very  short,  not 
excavated;  the  front  coxa;  arc.  contiguous;  the  tihiic  are  dilated,  and  finely 
serrate;  the  terminal  spur  is  very  small;  the  tarsi  are  slender,  wiih  the

HYLURGKJPS  n.  g. 

I  have  separated  as  a  distinct  genus  the  species  referred  to  Erichson's 
secvind  division,  having  the  third  tarsal  joint  broader  and  bilobed,  and  the 
mesosternum  protuberant.  They  are  quite  different  in  form  from  true 
Hylastes,  and  resemble  Deniroctonin,  the  prothorax  b  'ing  m  )re  narrowed 
forwards,  and  more  finely  and  densely  punctured.  The  basal  margin  of 
the  elytra  is  so  acutely  defined  in  //.  granulatu^  and  pinifex  that  I  should 
place  them  near  Ifi/lurgtm,  but  for  the  scutellum,  which  is  not  depressed; 
and  for  the  decider  antenna!  grooves,  which  remove  them  from  the  group 
of  Hylurgi.     The  front  tibiip  are  less  coarsely  serrate  than  in  7lj/lasteit. 

The  species  may  be  t'lus  distinguished  : 

Prosternal  ridges  acute ;  front  transversely  impressed.  9^

The  prosternivl  sutures  are  entirely  obliterated,  as  is  also  the  short  suture 
behind  the  posterior  point  of  the  prosternum.so  that  the  under  surface  con- 
sists of  but  one  piece.  The  coxal  cavities  are  rounded,  and  narrowly  sep- 
arated. 

Mesosternum  flat,  triangular  behind,  with  the  jKiint  rounded,  and  sepa- 
rating the  middle  coxse;  cavities  rounded,  epimera  transverse,  oblique,  not 
attaining  the  coxffi. 

Metasternum  long,  side  pieces  narrow,  or  moderate  in  width,  wider  in 
front,  with  the  outer  angle  prolonged  forwards;  in  many  genera  there  is  a 
transverse  impression  in  fhmt,  simulating  a  suture. 

Elytra  conjointly  rounded  behind,  and  forming  a  small  suturnl  fold, 
which  fits  into  a  deep  emargination  of  the  pygidium  ;  fold  of  the  inner  sur- 
face acute,  not  prolonged  much  behind  the  middle.  Epipleune  distinct. 
The  striie  are  ten  in  number,  with  a  short  scutellar  one  as  in  Carabida; 
this  scutellar  stria  is  usually  about  one-fourth  the  length  of  the  elytra,  and 
does  not  connect  itself  with  the  sutural  stria. 

Abdomen  with  five  free,  and  sometimes  nearly  equal  ventral  segments; 
sutures  straight;  intercoxal  process  triangular,  acute  or  rounded  in  front; 
dorsal  segment  membranous,  except  the  pygidium,  which  is  corneous,  de- 
clivous and  exposed  ;  no  .inal  segment  in  the  (^. 

Anterior  coxte  narrowly  separated,  globose;  middle  coxae  moderately  sep- 
arated, rounded;  hind  coxte  transverse,  not  prominent,  never  very  widely 
separated. 

Legs  slender,  front  pair  sometimes  elongated  in  (^;  tibias  truncate  at  tip, 
without  spurs  or  hooks. 

Tarsi  brush  like  beneath,  4-jointed;  .second  joint  triangular,  emarginate; 
third  joint  bilobed,  sometimes  large,  sometimes  small;  fourth  joint  slender 
with  divergent  claws,  which  are  either  simple  or  toothed. 

Our  genera  represent  four  tribes: 

Antennie  inserted  at  the  sides  of  the  beak; 

Prothoracic  ridge  not  basal tropiderisTi. 

Prothoracic  ridge  basal banitroi>I!«i. 

Antennae  inserted  on  the   front;  prothoracic  ridge 
basal ; 

Elytra  striate  as  usual ARiKOCERINI. 

Elytra  not  striate XENORCHESTINI. 

Tribe  I.    tropiderini. 

The  genera  of  thip  '-ibe  are  sufficiently  distinguished  by  the  position  and 
form  of  the  prothoracic  ridge,  whicli  is  remote  from  the  base,  more  or  less 
sinuous,  and  flexed  obliquely  at  the  sides.  The  antennie  are  situated  under 
the  lateral  edge  of  the  beak,  which  is  sometimes  flattened  and  expanded  so 
that  the  antennal  cavities  are  partially  covered. 

Three  groups  occur  in  our  fauna:

This  is  a  narrow  species,  with  the  base  of  the  i)rothorax  truncate;  there 
is  a  trace  of  a  second  transverse  raised  line  l)etween  the  base  and  the  ante- 
basal  ridge  ;  the  latter  is  situated  about  one-fifth  from  the  base,  slightly 
sinuate,  and  forming  an  obtuse  angle  at  tlie  middle;  fiexcd  obliquely  for- 
wards on  the  side,  where  a  distinct  latenxl  angle  is  formed  behind  the  middle. 
The  pubescence  is  yellowish  brown,  mixed  with  pale  gray,  and  does  not

The  sides  of  the  beak  in  the  insects  of  this  group  are  dilated  over  the 
antennal  cavities,  which  are  therefore  not  visible  from  al)ove.  The  form 
of  the  antebasal  ridge  difters  in  each  genus,  and  in  conjunction  with  the 
antennal  club  and  tarsal  claws  affords  easy  characters  for  distinguisliing  the

EURYMYOTER  n.  g. 

The  well-known  species  upon  which  this  genus  is  established,  represents 
in  our  fauna  the  European  Plnfi/rJiinui*,  but  differs  by  the  beak  being 
narrower  than  the  licad  and  strongly  dilated  at  the  tip  ;  it  is  uneven  above, 
with  three  wide  grooves  and  two  ridges,  extending  as  far  as  between  the 
antenna',  where  they  end,  leaving  the  dilated  part  of  the  beak  flat ;  the 
sides  are  extended  over  the  antennal  cavities,  which  are  small  and  visilde 
only  from  the  sides  and  beneath.     The  mandibles  are  flat,  acute,  and

ALLANDRUS  Leo. 

I  have  established  this  genus  uix)n  a  snuvll  Canadian  species  remarkable 
by  the  se.xual  differences  The  form  Is  as  slender  as  In  Tropidere»;  the  beak 
Is  longer  than  the  head,  narrower  at  the  bas*,  slightly  dilated  at  the  tip;  In 
the  male  It  Is  furnished  with  a  very  high  crest,  gradually  fading  out  In 
front;  In  the  9  cnly  an  obsolete  carina  Is  seen.  The  antenna'  In  the  9  ex- 
tend to  the  base  of  the  elytra,  and  are  just  as  In  Tropideres,  except  that  the 
second  joint  is  thinner;  joints  9-11  form  an  oval,  compressed  club.  In  the 
cf  the  antennoe  are  as  hmg  as  the  body;  .joints  3-8  elongated,  and  a  little 
thickened  at  tip  ;  0-11  flattened,  forming  ii  loose  club.  Tlie  prothorax  as 
in  Tropideren,  but  not  tuberculate  at  the  sides;  transverse  ridge  remote 
from  the  base,  feebly  curved,  and  subsinuate;  flexed  obliquely  forward  at 
the  sides.  Eyes  rounded,  lateral,  jjromluent.  finely  granulated.  Tarsi 
more  slender  than  usual;  third  joint  not  as  wide  as  the  second;  claws 
appendiculate  rather  than  toothed.  Mentum  with  the  lobes  wide,  nar- 
rowly rounded  at  tip;  ligula  large  and  coraceous,  filling  up  the  einargi- 
na'lon  of  the  mentum  more  than  In  the  preceding  genera,  (somewhat  as  in 
certain  Lebiini).

Group  III.     HormiMl 

The  genera  upon  which  I  have  founded  this  group,  seem  sufliciently 
distinct  from  the  other  Corrhecerides  of  Lacordaire  to  be  separated  from 
them.     I  would  define  it  by  the  following  characters: 

Beak  not  dilated  at  the  sides  over  the  antennal  cavities.  Eyes  emargi- 
nate,  not  finely  granulated.  Prothoracic  ridge  antebasal,  oirved  or  ob- 
tusely angulate  backwards  at  the  middle,  flexed  obliquely  forward  at  the 
sides.  Tarsi  with  the  first  joint  long;  second  triangular, scarcely  emarglnatc;

HORMISOUS  Wollaston. 

In  this  genus  the  form  is  cylindrical  and  less  slender  than  in  Tropideren. 
The  bci :;i  is  broad  and  flat,  not  longer  tlian  the  head,  with  the  antennal 
cavities  lateral,  not  covered  by  the  sides.  Ej'es  rather  large,  less  finely 
granulated,  oblique,  feebly  emargiiuvte;  antenna' alike  in  both  sexcs.hardly 
extending  to  the  base  of  the  prothorax,  club  oval,  apparently  solid.  Pro- 
thorax  scarcely  longer  than  wide,  gradually  narrowed  in  front;  more  rap- 
idly narrowed  behind  the  transverse  carina,  which  is  slightly  oblique,  par- 
allel with  the  base,  and  ends  each  side  in  a  lateral  cusp. 

1.  H.  Ba'*ator,  n.  sp. 

Brownish  black,  mottled  with  spots  and  bands  of  cinereous  pubescence; 
prothorax  densely  and  finely  punctured;  elytra  with  rows  of  large  and  deep 
punctures,  about  t\\  ice  as  long  as  'he  prothorax.  Length  1.2-1.0  mm. ;  .05 
-.07  inch. 

Middle  and  Western  States,  not  rare;  I  have  adopted  the  specific  name 
with  which  it  is  labeled  in  the  collection  of  the  iate  Dr.  Zimmermann. 
There  are  few  jirominent  characters  in  this  singular  little  insect,  except  such 
as  are  of  generic  value.  It  agrees  with  the  Galipagoan  //.  vnriegatus  in 
having  the  transverse  ridge  of  the  prothorax  broadly  angulated  at  the 
middle,  but  the  latter  differs,  according  to  description,  in  color,  and  in 
liaving  the  elytra  indistinctlj'  punctato-striate.  The  specimens  vary  greatly 
in  appearance,  according  as  the  pubescence  is  more  or  less  abraded.  In  the 
best  preserved  individual,  the  prothorax  is  mottled,  and  the  elytra  also,  but 
the  mcttlings  of  the  latter  are  arranged  so  that  a  subscutellar  sjjace  on  eafh 
elytron,  and  a  broad,  post -medial  band  not  reaching  the  margin,  are  left 
free  from  cinereous  spots.  The  posterior  transverse  carina  of  the  prothorax 
Is  slightly  oblique,  forming  a  very  obtuse  angle  backwards  on  the  median 
line,  and  projects  at  the  side  as  a  small,  sharp  cusp. 

TOXOTROPIS  n.  g. 

This  genus  is  closely  related  to  Hormtscus,  and  in  fact  on^y  differs  from 
it  by  the  antennal  club  which  is  elongate-oval,  compressed,  and  composed 
of  three  distinct  joints  equal  in  length.  The  eyes  are  rather  finely  granu- 
lated, and  only  feebly  emarginate;  the  antennal  cavities  are  small  and 
rounded.     The  antebasal  ridge  is  regularly  curved  in  an  arc  of  a  circle,  for

1.  T.  pusillus,  n.  sp. 

Of  the  same  size,  form  and  color  as  HormincuH  mltator,  brown,  varied 
with  j)atclic.s  of  line  white  jmbescence;  eyes  larger  and  more  i)rominent; 
pr.)lhorax  more  finely  punctured.     Elytra  with  striiu  of  rather  large  punc 
tures;  interspaces  even.     Length  1.2  mm.;  .05  inch. 

Tampa,  Florida,  one  specimen,  Mr.  E.  A.  Schwarz. 

2.  T.  approximatus,  n.  sp. 

Of  the  same  form,  color  and  sculpture  as  T.  pusilhiit,  but  the  antebasal 
ridge  is  less  carved,  and  therefore  is  more  parallel  with,  and  nearer  to  the 
base  than  in  that  species.  The  hind  angles  near  the  base  are  therefore  less 
prominent,  and  the  body  is  somewhat  stouter.     Length  1.5  nun. ;  .00  inch. 

One  specimen,  San  Diego,  Cal. ;  Mr.  G.  R.  Crotch. 

QONOPS  n.  g. 

This  genus  is  also  related  to  the  two  preceding,  but  differs  from  Ilormis- 
ciwbythe  antennal  club  compressed,  and  composed  of  three  joints  equal 
in  length;  the  antennal  cavities  are  small,  and  the  eyes  are  deeply  emargi- 
nate  and  rather  finely  granulated.  It  dift'ers  fron^.  both  by  the  claws  being 
clet\  almost  to  the  base,  with  the  inner  portions  converging  as  in  Anthono- 
mu8.  It  also  ditfers  from  all  the  other  genera  in  our  fauna  by  the  middle 
and  hind  tibiie  being  armed  with  a  small  mucro  or  spine  at  the  inner  side 
of  the  tip.  The  form  is  a  little  stouter  than  in  llormucus;  the  antebasal 
ridge  of  the  prothorax  is  curved  in  the  arc  of  a  circle;  towards  the  sides  it 
Is  nearly  transverse,  and  ia  not  flexed  forwards. 

1.  Or.  flssunfifuis,  n.  sp. 

Oblong,  rather  robust,  brown,  mottled  with  small  spots  of  yellowish 
gray  pubescence.  Head  and  prothorax  opaque,  very  densely  and  finely 
punctured;  the  latter  a  little  wider  than  long,  narrowed  from  the  end  of 
the  ridge  forwards,  but  scarcely  rounded  on  the  sides;  rapidly  and  con- 
cavely  narrowed  behind  the  ridge,  the  end  of  which  forms  an  acute  lateral 
angle.  Elytra  not  wider  than  the  widest  part  of  the  protharax,  convex; 
stria;  composed  of  moderate  sized  punctures,  int(;rspaces  very  finely  punc- 
♦  ulate.     Length  2.5  mm. ;  .10  inch. 

Three  specimens  from  Big  Trees,  California;  sent  ">y  Mr.  James  Behrens 
to  Dr.  Iloin. 

Tribe  II.    bahitropixi. 

The  only  ch.inici?rs  of  a  general  kind  which  can  be  given  to  distinguish 
this  from  the  other  tilbeS;  are  that  the  antcniue  are  inserted  under  the 
sides  of  ih(  beak,  and  that  the  prothoracic  ridge  is  quite  basal,  causing  the 
surface  behind  it  to  become  perpendicular ;  it  consequently  attains  the 
hind  angles,  and  is  there  flexed  forwards,  not  obliquely  and  at  an  obtuse 
angle,  but  rectangularly.  As  a  farther  consequence  of  this  arrangement, 
the  basal  margin  of  the  elytra  is  acute.

This  species,  first  described  from  Brazil,  occurs  in  Missouri  and  Texas. 
It  dill'ers  from  the  following  in  the  proportions  of  the  antennal  joints,  but 
not  suffleiently  to  place  the  species  in  separate  genera ;  the  markings 
of  the  elytra  are  similar,  but  in  the  presi'nt  species,  in  well  preserved 
specimens,  there  is  a  grjaer  condensation  of  ochreous  pubescence  along  the

prothorax  is  deflexed,  it  might  be  supposed  that  the  transverse  ridge  was 

not  absolutely  basal.     The  same  is  the  case,  though  to  a  less  extent,  in  the

Tribe  IIL     AR^KOCcnixi. 

But  two  genera  of  this  tribe  have  occurred  in  our  fauna  ;  they  are  of 
small  size,  and  are  easily  known  by  the  antennte  being  inserted  in  small 
foveiE  upon  the  upper  surface  of  the  beak.  The  transverse  carina  of  the 
prothorax  as  in  the  preceding  tribe  is  basal,  suddenly  flexed,  forming  a 
right  angle,  and  extended  a  short  distance  along  the  sides  ;  the  antenniu 
are  slender,  and  the  last  three  joints  form  a  loose  club.  The  elytra  are 
regu'arly  striate  as  in  all  the  preceding  tribes  and  groups  of  the  family.

Th(!  si)eciea  of  this  family  are  small,  and  have  a  peculiar  and  easily  re- 
cognized appearance.  Lacordairc  has  placed  them,  as  a  tribe  near  his  Atte- 
Idhides,  with  whicli,  however,  as  will  be  seen  by  the  foregoing  description, 
they  have  but  little  resemblance,  or  affinity. 

Lacordaire  describes  them  as  apterous  ;  in  all  the  species  I  have  examined 
the  wings  are  (piite  well  develo;'ed.  I  also  find  that  in  many  of  our  species 
the  claws  are  toothed  or  api)endiculate,  while  in  a  few  they  are  simple,  and 
I  have  therefore  attempted  to  group  them  in  mj' collection  upon  those  char- 
acters, the  position  of  the  antenniu,  and  the  relative  leng'  f  the  flrst  and 
second  joints  of  those  organs. 

The  s;:ecies  are  numerous,  and  many  are  yet  und.  d.     It  seems 

hardly  worth  while  to  affix  names  to  them,  until  they  have  been  collected, 
with  referenci!  to  the  i)lanls  wliich  they  infest.  I  will,  therefore,  on  the 
present  occasion  give  only  the  bibliography  of  the  described  species,  in  al- 
phabetical order,  with  such  notes  on  their  habits,  as  I  have  been  able  to

ft  dillers  from  P.  ciniiplitK  not  only  by  the  color  but  by  the  first  joint  of  the

is  also  thicker  and  the  club  larger  than  in  that  species. 

The  scales  in  this  species  are  deeply  cleft  almost  to  the  base.  Since  the 
printing  of  that  part  of  this  memoir  which  relates  to  the  present  genus,  I 
have  examined  more  closely  the  scales  of  the  different  species  i;i  our  fauna

b.  Scales  dislinctlj'^  striate,  with  longer  narrow  ones  intcnnixed,  which 
are  the  bristles  of  the  elytml  interspaces.  These  bristles  are  obtuse  in  qiidd-

It  is  apparent  therefore,  that  valuable  characters  maybe  fornd  for  the

of  the  scales.

This  species  has  a  slender  form,  and  is  clothed  with  ratli'.T  coarse  grayish 
pubescence,  with  a  stripe  of  paler  color  at  the  sid;'3of  the  [)rotiiorux  and  ely- 
tra. The  beak  is  cylindrical,  rather  stout,  about  twice  as  long  as  the  head, 
punctured,  carinate  for  one-half  its  length  without  fovea  between  the  an- 
tennffi  ;  frontal  groove  short,  deep,  antenna;  inserted  one-fourth  from  the 
tip,  black  ;  funicle  stout,  first  joint  but  little  longer  than  the  second,  which 
is  scarcely  longer  than  the  third.  Prothorax  one-third  longer  than  wide, 
gradually  narrowed  from  the  base  forwards,  sides  straight ;  punctures  large, 
shallow,  approximate,  disc  longitudinally  broadly  and  somewhat  deeply 
excavated  towards  the  base  ;  medial  angle  produced,  obtuse!y  rounded. 
Scutellum  not  visible.  Elytra  a  little  wider  than  the  piothorax,  sides 
rounded  near  the  base,  then  converging  behind,  tips  separately  slightly 
prolonged,  and  acuminate  ;  striie  composed  of  distant  punctures,  mos.ly 
concealed  by  the  coarse  pubescence.     Length  7.6  mm.;  M.)  inch.  * 

Arizona  and  Lower  California.  This  species  is  as  slender  as  L.  rubeUiiii, 
but  the  tips  of  the  elytm  are  only  slightly  prolonged,  and  the  other  char- 
acters are  quite  ditterent. 

I  neglected  to  mention  that  the  third  joint  of  the  tarsi  in  L.  ph  uridin  and 
texan'is  is  much  less  broadly  dilated,  and  the  lobes  are  less  obtusely  rounded 
than  in  the  species  of  division  C.  The  lobes  therefore  envelop  more  closely 
the  base  of  the  fourth  joint,  thus  shawing  a  transition  from  Clcotom  to  Lix- 
us, which  would  probably  warrant  the  separation  of  these  species  as  a  dis- 
tinct genus. 

The  first  part  of  the  table  might  be  modified  to  indicate  this  ditfcrcnce, 
which  is  better  than  the  characters  I  have  used  on  p.  154.

Another  specimen  from  Florida  agrees  in  form  and  sculpture,  but  differs 
by  the  beak  more  finely  punctured,  or  rather  puiictulate,  shining,  and  very 
slightly  pubescent.  The  basal  excavation  of  the  prothorax  is  larger,  less 
deep  and  vaguely  channeled  ;  the  medial  angle  is  equally  acute  and  i>ro-

rounded  to  the  tip,  which  is  tul)ularly  constricted  ;  hind  angles  not  pro- 
duced ;  disc  densely,  but  not  coarsely  punctured.  Elytra  with  striie  com- 
posed of  approximate  punctures,  interspaces  feebly  convex,  wider  than  the

Of  the  same  size,  form  and  color  as  the  large  form  of  N.  bicolor,  but  the 
beak  is  more  strongly  and  densely  punctured.  The  prothorax  is  very  finely, 
almost  imperceptibly  pubescent,  more  coarsely  punctured,  with  the  sides  and 
two  small  apical  spots  testaceous  :  the  lateral  cusp  is  prominent  as  in  N.  bi- 
color. Elytra  with  stria;  composed  of  larger  punctures ;  the  dark  markings  are 
very  distinct,  and  quite  difterent  in  pattern  :  there  is  a  cloudy  and  ill-de- 
fined spot  behind  the  scutoUum  :  then  an  oblique  band  formed  by  elongate 
spots  on  the  2d,  4th,  Oth  and  8th  interspaces  ;  then  a  large  apical  blotch, 
occupying  one-half  the  surface,  with  an  oblique  anterior  outline,  parallel 
with  the  oblique  band  ;  the  pale  color  extends  into  this  blotch  along  the  4th 
interspace  for  some  distance  ;  this  dark  blotch  includes  some  small  spots  of 
lighter  brown,  and  is  also  paler  at  the  sides,  along  which  it  extends.  An-

being  unarmed,  and  by  the  elytral  spot  not  being  narrowed  at  the  tip,  but 
also  by  the  form  of  body  which  is  elongate  and  subfusiform,  while  in  P.

Enterprise,  Florida  ;  one  specimen,  Mr  E.  A.  Schwarz.  The  scales  have 
been  removed  by  abrasion,  and  only  a  few  remain  near  the  base  of  the  ely- 
tra, and  the  sides  and  base  of  the  prothorax.  Tlie  apical  constriction  of  the 
prothorax  does  not  continvie  across  the  prosternum  as  in  tiie  otiier  species, 
and  as  in  all  Gentrinus  known  to  me,  but  disappears  in  the  apical  margin, 
thus  leaving  the  front  part  of  the  prosternum  flat.  This  should  probably 
be  considered  a  generic  ditference,  but  I  am  unwilling  to  separate  it  witli- 
out  liaving  better  preserved  specimens  for  study.  The  claws  seem  to  be 
very  small,  bi    'ardly  connate  at  base.

spaces finely  punctured,  beneath  strongly  jiunctured,  thinly  clothed  with 
small  whitish  scales.     Length  B.2  mm.;  .18  incli. 

Nebraska,  one  specimen  ;  given  me  by  Mr.  Ulke.  I  confounded  this 
species  with  B.  fiUforme,  which  it  resembles  in  the  form  of  the  prothorax, 
but  differs  by  the  stronger  pvmctuation  and  by  the  elytra  being  distinctly 
wider  than  the  prothorax  just  behind  the  base  ;  the  scales  are  also  whiter 
and  larger,  and  the  elytral  strite  are  deeper. 

These  four  species  may  therefore  be  distinguislied  as  follows  : 

Body  very  narrow,  filiform,  elytra  not  wider  at  base 
than  the  prothorax,  which  is  densely  but  not  deeply 
punctured,  scales  very  small,  gray,  denser  at  the 
sides  of  prothorax  and  elytm V  filiforme. 

Body  very  narrow,  prothorax  strongly  and  densely 
punctured,  suddenly  narrowed  in  front,  scales 
of  elytra  oval,  whitish,  not  very  small 4.  quadrloolle. 

Body  linear,  but  less  narrow,  prothonix  densely,  less 
coarsely  punctured  ;  elytra  a  little  wider  than  tlie 
protliorax  at  base,  scales  very  small,  rounded,  yellow- 
gray  2.  lineare. 

Body  as  in  Ji/K'arf,  but  the  elytra  are  more  conspicuously 
wider  near  the  base,  and  the  scales  arc  elongate, 
white,  and  form  stripes ;  prothorax  more  coarsely

TRIOHISOHIUS  n.  g. 

This  genus  is  founded  upon  one  species,  which  agrees  with  Sphenoph- 
orui,  except  in  the  following  characters  : 

The  inner  side  of  the  front  and  middle  coxae  and  the  middle  of  the  meta- 
•tcrnum  and  the  first  and  second  ventral  segmentsare  clothed  with  longhair; 
the  thighs  beneath,  and  the  tibiue  on  the  inner  side  are  fringed  with  long 
hair  ;  the  genital  segment  of  the  ^  projects  (as  in  llhyni'hophorus)  and  is 
fringed  with  hair  at  the  tip.  The  third  joint  of  all  the  tarsi  isslender,  notat 
cU  dilated  <^r  eniarginate,  glabrous  beneath,  fringed  at  the  sides,  and  quite 
as  long  as  the  secoad  joint,  which  is  equal  to  the  first. 

The  ppothurax  is  uniformly  punctured,  without  impressions,  but  with  a 
narrov  smooth  dorsal  line,  and  the  elytral  stria;  are  deep  and  crenate  ;  the 
inierspacts  are  t;ven,  and  scarcely  punctulate. 

1.  T.  crenatus,  n.  sp. 

Black,  subopaque.  Beak  scarcely  more  than  half  the  length  of  the  pro- 
thorax,  .slender,  slightly  curved,  finely  punctured,  wiih  a  very  fine  longi-

Body  narrow,  linear,  rather  flat,  sparsely  pubescent.  Beak  parallel, 
cylindrical,  separated  from  the  front  by  a  distinct  impression  ;  eyes  rather 
large,  transverse,  coarsely  granulated,  situated  on  the  sides  and  under  sur- 
face of  the  head,  not  visible  from  above.  Antenna;  inserted  about  the  mid- 
dle of  the  beak,  short  and  stout,  scape  attaining  the  eyes  ;  funicle  first  joint 
large,  2-7  very  short,  closely  connected,  club  small,  oval,  shining,  sparsely 
hairy,  annulated  only  at  the  tip.  Metasternum  rather  long ;  front  coxae 
widely  separated,  the  others  still  more  distant ;  tibite  with  the  terminal 
hook  very  large  ;  tarsi  rather  short,  third  joint  but  little  wider,  somewhat 
bilobed. 

The  genus  has  thus  far  occurred  only  in  Jlalabar,  and  rh<didonotu», 
which  immediately  follows  it,  is  found  in  Borneo.  It  appears,  therefore, 
to  be  a  third  instance  of  that  remarkable  distribution  which  I  have  pre- 
viously mentioned  in  the  Heteromerous  genera  Othniua  and  hchalia. 

1.  H.  errans  n.  sp. 

Very  elongate,  reddish-brown,  nearly  opacjue,  thinly  clothed  with  coarse 
yellowish  hair.  Beak  a  little  shorter  than  the  prothora.\,  rugosely  punc- 
tured, transversely  impressed  at  the  ba^e.  Head  finely  punctured.  Pro- 
thnrax  more  than  one-half  longer  than  wide  ;  widest  near  the  base,  sides 
suddenly  rounded  behind  the  widest  jiart,  but  gradually  obliquely  nar- 
rowed in  front  and  nearly  stmight  ;  sliglitly  constricted  near  the  tip  ; 
disc  rather  flat,  densely  and  coarsely  punctured,  without  impnssions  or 
dorsal  line.  Elytra  not  wider  than  the  wideet  part  of  the  prolhorax,  trun 
cate  at  base,  scutellum  not  visible,  sides  paniUei,  rounded  at  tip  ;  striae 
deep  and  l)road,  punctures  large,  quadrate,  interspaces  very  narrow.  Body 
beneath  very  coarsely  punctured ,  punctures  of  ventral  segments  not 
smaller.     Length  2  mm. ;  .08  inch. 

District  of  Columbia  ;  collected  by  Mr.  Ulke.  I  owe  a  specimen  of  this 
interesting  species  to  tlio  kindness  of  Dr.  Horn.

APPENDIX    IV. 

The  following  bihliogriiphy  of  llif  memoirs  reliiting  to  Econnmic  Eiito- 
iiiology  of  tlu!  Uhynchoplioru  of  the  Lulled  StiiteH,  has  boea  prepiiied  at 
my  re(iue»l  by  Mr.  H.  Plckmiin  Miiiiii,  of  CiinibrUlge,  Muss. 

It  will  be  un  iiiviiUmble  addition  to  this  volume,  for  ail  who  desire  to 
study  the  habits  of  these  insects:  a  prerequisite  to  any  rational  enquiry 
into  th(!  means  to  be  adopted  for  the  supijression  of  the  noxious  species. 
Such  a  study  has  been  heretofore  almost  impracticable  in  this  country,  in 
consequence  of  the  large  number  of  undescribed  si)ecies,  and  the  scattering 
of  the  descriptions  of  those  which  have  been  named  in  a  multitude  of  vol- 
umes, many  of  which  can  only  be  obtained  with  much  labor  anil  great  cost. 
For  the  proi)er  use  of  the  tables,  certain  explanations  arc  necessary. 

I.  The  subjects  mentioned  in  the  articles  cited  are  indicated  as  follows  : 
b.  benefits.  d.  description.  /.  food. 

h.  habits.  t.  injuries.  /.  localities. 

r.  remedies.  «.  seasons.  t.  transformations. 

II.  The  *  after  a  reference  indicates  that  the  article  is  illustrated  with  a 
figure  of  the  insect  in  question.
